Milling machine

One of the most common work of milling operation checkout and final machining on component parts production.

All objects and components used the most basic to the most advanced human tools, including automated, hammer, etc. Such methods have been produced which may not be carried as a benchmark or filings. Manufacturing methods that chip in them may be linear or rotational motion can have a milling machine, including devices with circular motion. Machine milling machine is a tool for creating complex shapes for the piece of metal or other solid materials such as plastics and high density. Workmanship of this device is so that the cutting tool has come from the times piece and rotated and placed on your piece for which it can be move.

To disconnect from the chip work in a couple of the blades the edge milling machine that used it blade milling. The winning edge milling blade forms a wedge (like the grate turning) that are located on the perimeter of a circle.

In any one of the edges of the milling machine milling blade while his era promenade a short chip to the next turn of the dial and no free circulation of cool has taken filings; hence the blade shank cutters such as grate turning permanent incision under pressure are not supposed to, and download filings with them Can be done faster.

A variety of milling machine:

Milling machines depending on the main blade axis milling horizontal or vertical it is horizontal or vertical milling machine names to be called. Circular motion in horizontal milling machine may use a transmission or a motor and gear box for the series and single-building tasks. Vertical milling as well as in cases where the floor form a single building, masonry or not possible by horizontal milling are milling head and use the gear as well as the ability to rotate 45 ° in both directions. This table also has three longitudinal and transverse and vertical motion with arm or automatic operation. The versatile milling is also another type of this machine with an additional device mount can be used instead of the vertical milling machine. This table can be 45 degrees to the left and right. For complex tasks such as masonry screws, rather than a spur gear, razor shave is also of special milling machine is used. Including all special car can be used to copy milling pointed out that has two axes and one located on the model and the other a new piece on the trashd model.

Today the use of milling machine screw is on the rise. The improvements obtained in machining tools, milling machine threaded turns out to be an important process in different applications of piercing, such as space, defense, medical and computer industries.

Division of milling machine:

Four move on to the milling machine takes place.

Rotational motion or motion axis milling milling blade that workflow.

Move the longitudinal and cross-section table by hand or automatically.

Move the amodber axis milling shifts up or down.

Change and progress speed

Depending on the workpiece material, the diameter of the blade cutting speed of milling and grinding away the remodel progress speed adjustable table and change. When the car is off the table with respect to leverage available in any car can be far away and low or high speed of progress.

Depending on the workpiece material, the diameter of the blade cutting speed of milling and grinding away the remodel progress speed adjustable table and change. When the car is off the table with respect to leverage available in any car can be far away and low or high speed of progress.

The constituent components of milling machine:

The device divisions including the drag line or create a gap and so it is done by dividing the device say that is composed of the following components:

Fixed trunk that other parts of the Fest is mounted on it.

The axis of the work that the work the wheel axis on one side of the snail and the other to the head it can be.,., and three work to close the system.

3-wheel gear 40 mostly snails.

The snail

Split screen: each device is usually divided into three split screen has has holes which are divided into basic role in the work piece, and sometimes for convenience both sides perforated pages.

Categories: cochlear axis to rotate the handle to get the divisions are calculated. This category has a crack that nut and sliding by unlocking the nut can be short or long handle arm. The aim of this work is putting the devil in front of a circle that is the number of holes required.

Rocket (the devil k): rocket attached to the category is divided into fixed and to keep the page and specify the necessary holes.

Compass: on the axis of split screen and plugs it each time to the number of holes required to open.

Holes for holding split screen.

Split pin for direct.

Split screen to direct divisions.

Stuck and tip page..

The pieces of work.

Blades for milling.

After setting the device and observe the safety tips can be found by using a thin screen between the piece and the blade milling milling blade can be used with a piece of the tangent. Then chip method, along with the operation (push) or reverse.

In order to move ahead on the table pressure load device (piece work) and also the direction of the blade during milling, milling blade together first, and then the thick thin chip chip. Hence the initial impact is harsher, and on the other hand it is possible to be drawn the following milling workpiece is very likely the serrated blade milling will fail. This causes the machine to load agrees are made strong and should by no means freedom in the navigation or not they found bead mill. Including the benefits of this method can be used to reduce energy consumption and better surface smoothness is the ability to cut thin pieces of its flaws and pointed out the lack of ability to chip level spare parts go harder work. In the opposite direction of the reverse operation method of filing the blade circulation once the milling and chip gradually becomes thick and pressure to the blade. This method for advancing the blade opposite the workpiece during milling and shear force tried to separate the pieces of work are so desks work piece surface a little shimmer will be one of the cons of this method.

Term milling machine:

In the milling machine milling grade 2 work in Iran, someone who is able to do the combination of the following matters: milling machine, map reading, measuring the degree of welding, arc, setting up milling machines, rotrash, stepping razor, shave, carefully working up front Norma 5% mm grooves, razor, shave the slope  And they control the precision of 5% mm, polygon down parts, simple gear shaving mm, Gears of conflicts (differential), a simple shoulder gear shaving and shaving tracks and tilting Screw Gears, milling machine parts with divider, the arch masonry, types of thorns and jakhar, line drawing, drilling and Based on work by powerful milling machine and related machinery maintenance service.

Brushed ohazar woman handling hub operations?

Brushed ohazar woman handling hub operations? Making gears in different ways can be one of these methods is the head of a woman and this is the purpose of the hub is used. A typical hub device that is using the milling machine it can be woman ohazar gear spur production hub devices can rotate the tool oghtah to work with a specific period of time as Deputy Minister and to create the gear tool used for this practice to be a winner to create the shape of the cross section Dent and for spiral gear corners so the tool on the workpiece shape of the curve.

Dent placed on cutting tool around a cylindrical form and snail gears as well as contact with a snail does.

Performance and the implementation of this process to the work piece in a case that has to be fixed will be closed and CNC tools into a reciprocating motion of the workpiece on the Dent. 

At the beginning of the start of machining and CNC lathe tool operations is set to the raw distance of gear and then the appropriate tool to the workpiece to the desired depth of the indentation can be created. After this step the CNC tool parallel to the axis of a helical gears can be fed raw with a rotation of gears are made of raw, Dent & nutrition tools in the appropriate width the width of the pinion gears to raw gives as well as turning the gear Helix angle of helical gear teeth it is necessary to CNC axis deviation added.

Use a thousand more applications of the spur is much omamola power transmission for a hit, but our goal is that asest this process in such a way that we become a force for transfer to the system software and gears as well as high pressures.

For example, it can be a head plus car noted that the immense force and acts for a hit, but the force applied to the wheel by plus is software and not for high pressures and the ability to blow as well.

Boring

Boring: one of the most diverse machining procedures that in parts of big and heavy and where turning, milling machine, drill and what is not possible is used. It's like (the frame of machine compartments and other engines). If the table is a tool to rotate horizontally chip operation.

Boring boring operations: operation should be on pieces that have a basic hole requirements. This drill hole is created by or through casting, forging, or there's been extruded. This method is used mainly for items that have a good level of quality and dimensional telorance package is needed. With this method it can be abrasive blasting operations and milling machine, it either on the exact details. It also can be operational with this method because it is turning, grinding (sanding) ochrkh've done parts on razor gear.

Different types of boring machines:

Horizontal boring machine:

-Fix the workpiece on the machine is bdorood of instruments it rotate. -With the use of this machine can be a lot of things because of electrical work, screw-turning-stamping – polishing and Groove a woman discovering the boring oprderdsr. -Can be frustrated with this method of symmetric parts easily kept on the device and machining operations (e) on the n.

Vertical boring machine

-The vertical workpiece on the table during a car makes of instruments fixed in place. -The large pieces and mostly boring ride on this machine. -In this type of machining multiple tools can generate high rates.

CNC wire cut (Electrical discharge machining) is a device that is a thin wire by the (mainly 25 microns) inside the dielectric liquid (distilled water) on the cutting workpiece. electric energy for creating a quick spark between the workpiece and the wire will cause melting of the moment "burning away" of this point. The melting action inside a dielectric fluid. The role of dielectric coolant, wash and keep wire is perpendicular. Work piece material can be soft like aluminium, copper and brass, as the hard steel, tungsten and even do (diamond). This has been a visible spark and when clean water is becoming a chip carving Micron rhodium plating can be seen clearly. This feature is unique to wire cut because there is no physical contact between the wire and there is no work and always have a gap (GAP) between the wire oghtah there so little tool error and so rigor.

The role of transmission wire cut spark wires and must be of sufficient strength and good conductivity. Have two type of managed consumption there is no turning back orfat wire. Copper wire cut in strings of brass with different coatings or zinc and zinc oxide bi formulas for a better cut. China, Taiwan and Korea spree recently is a good provision of products. These wires with different tension usually "900-500 and two have been made because of the Newton > Burnout pace jerfh with size just disposable. reciprocating mostly strings" molybdenum compounds

Otngsten. omamola "in the Chinese application machines.

The geometry of the piece that should be cut is usually "at one point often" in Corel Draw and AutoCad drawing format. This drawing format (DWG) or (DXF) can be recorded. this file is opened in the application according to Weber's ESPIRIT lines, arcs and circles as the orbital path of a left or right turn to the NC or ISO file The text file has been. and the basis of the work of the باG-file Code that is available to the line and shape of the arches (arches). Vine is the same as the original three car language. this language is based on the order: the order of moving straight line (G01 X, Y.) (G02 X...,Y...,I...,J...) ...) Move command coordinate with CCW end X bows ..., Y ..., and I respect that..., J. .. (G03 X...,Y....I...,J ...) Move command coordinate with chpgard the end of the X-bow ..., Y ..., and I respect that..., J. .. And it moves according to the order of the pines {(the middle piece required) with an offset from the outside} or matrix {(outer piece required) with an offset of you} automatically counting the diameter of wire and jerfh chat.

Being perpendicular to the wire in wire cut machining with the importance of the work of the modern machines in many vine CHARMILLES geometric method and automatically done simple and interesting and get different altitude ophthalmic Center up and down completely "in a context. to create two-axis angle U_axis and Y_axis To top gay head added that by changing the values of the desired angle of the axes.

These values by G-code to the machine and the machine according to the value of the angle and axis vartefaa to consider the position of the car change. these acts in the way GEOMAX using a top and a bottom contour contour independently with the height H of the piece can be done with this interesting ability Be different forms with fragments at the top and the bottom.

The country of the manufacturer of this device can be applied to Switzerland and Japan, Spain and Taiwan and China recently pointed out, such as the Japanese Mitsubishi CNC wire cut although, Sodic, Fanuc and good of its kind of interesting initiatives, but they have a lot of fortunes and the cause of it also welcomed Iranian artisans of wire cut by making Switzerland especially CHARMILLES. wire cut that this in 90 ad with 100 series models have entered Iran due to good accuracy, simplicity and high performance work, rest and the availability of repair parts and service good and skilled jobs have taken into consideration new series though.  The plant is one of the masterpieces of European design and industry, but for some reason in Iran, including a high price less available.

CNC wire cut features:

One of the benefits of dedicated CNC wire cut electrical discharge in the form of work. With this method, the spark, such as pressure on the workpiece and device-centric, and these devices for micron to Micron and as long as that takes command of your computer, without any error in your path moves with this advantage can be a variety of precision parts and dies a pines and The plastic matrix and designed and implemented., for example in the stage cannot be more wire cut CNC milling machines with the rest even compares. because all the same length and height as the chip operation. This ability in CNC milling machines or any of the CNC can not be viewed.

CNC wire cut limits:

The complexity and high cost, while being an expensive wire cut systems investment to make this device work in sensitivity and high maintenance cost can be make all the following systems should be constantly respected. controls and switches, if service. The smallest hitch causes the next great ahmal.

Operational skills, the operator, while the use of wire cut should be the dominant piece on Weber automatic mastering device.. Neglect of the smallest tip causing rot okhosart piece. It features a smart operator, detailed, tiny, bahoslah and trained the quest.

Filtering the water, cut the fine particles cause permanent deposition Micron rhodium plating on all tanks and motor device axes. Although water filter with the water flow path of the particles in the filter holes will be collecting device amabsth are always some particles in different parts of the deposition and cause trouble.

The lack of water pressure due to the transfer of a piece, view on the Canal-cutting machining of high osrat more گاید and nozzle must be close we piece so no direct visibility on the piece. so to avoid possible errors are excluded from direct control.

Permanent water flow pressure-filled and taken the Rocky deposits cause the channels, gay, gay tube leakage and taken and chmpr holes are and should be sure to "check and check and service specific times in the past" are interchangeable.

Electrical conductivity of water Conductivity Electero diunaising = E. C the release of suspended metal ions in the water increases the device regularly "(first distilled water E. C = 0 C = around (E. 35 though to reduce the ions of the resin mix (mixed ionic and cationic Annie) is gets used but these resins, and expensive And mrteba should be replaced if climbing E. C while cutting down speed parts rust and deterioration of many pieces can make.

The relatively high price of wire cut machine motor controller osaroo.

The falling pieces in the end working

Another disadvantage of the low speed machining device, which can not be with the C C.N. milling or laser and water jet competition. Although modern devices have more speed but limited due to high price of economic competition.

Low-speed low-cut primary loads: where high load and high precision is working both sides of the wire but for times of low edges needs to slow.

CNC stands for computer numerical control in Iran, these machines are CNC read empty, but their names to English machine (machine) translation of numerical control.

The first generation of these devices have been NC IE PC and device-specific commands according to understand the rationale for example with the use of punch cards.

For example, in order to advance this lathe for the action to be supported by the device, part of the handle towards the front in the car spinning into the NC punch work by a series of commands on the bar took place in punch, modern CNC machines you by a code.

So a simple handheld device CNC machine is virtually the same, which is the ability to code and command vulnerability through the mathematical logic in this device is the presence of the user (operator) to work with the device is limited to stand this person behind the device controller section and write a program once, just for one motor Other devices, does this automatically as many times as we want to repeat the course without the presence of the user.

The body of the machine is almost like handheld devices have a CNC milling machine is virtually the same hardware manual body is CNC milling lathe and CNC as well as for rock and. ..

The only difference is the controller section being added (of course, this book is a general difference, but also for specific electronic sector certainly has changed)

But the main part of this section, the controller, a CNC machine is the name of this industry segment is called an automatic CONTROLER CNC devices of any type (CNC, milling tools, stone Sharpener, injection, presses, etc.) More control with the kind of training that is certainly known lersh to individuals on the basis of data on the principle of automatic this device e.

Automatic CNC machines available for several such as fanvk-Haydn milling CN, Siemens-C39-2P22-C15-fagoro Mitsubishi and. ..

Siemens and Hayden have such brands milling CN that abundant in Iran are used but these are differences in how it is

The logic of the code found in the book a package of information that begin with G code example G01 G02 and G03 linear motion is the movement of the 1960s and the G90 absolute coordinates in terms of type of being or being relative specifies.

The codes as codes are special codes in General according to the type of controller is the difference between code تماید number, perhaps as an example in the G20 in order to choose the Siemens measurement system is metric but it's Haydn milling CN gives this code G70 amajam so as mentioned of training codes should According to the type of controller to be thankful that the master of the servant at the University under Siemens coding and models showed us to the top of the mark.

But what should really be at the University of the instruments should be amokht

The basics of the body of the device and format

The basic principles of the code as an example of how to code the most simple example is still code G01

For example, in the command line type lathe would be

G01 X20 Z-30 F10 S100 M7

Machine tools to this point, with the speed of 10 with any preset with vakhd spindle speed and. .. Raises the

The initial orientation, for example with the logic should be selected that is the relative or absolute measuring system or even be metric or not polar side codes to specify speed, etc.

How, for example, a workgroup is selected under the program will be written to the device must go to different places and after operations in Ann a place with a special action group, repeat, for example, to do this the following is a written program that should be on every device they position Do side jobs, such as the introduction of the M codes that turn on the pump and cooling substance.

Solve a few examples of different parts in the lathe and apply even in a farzo other device such as a stone or a query, the example must be such that the user simply bring an understanding of how to get the job done.

The machine tools that were forwarded to the name of the computer-assisted CNC. CNC precision gradually help needed for the production of complex parts in different industries such as aerospace and molding. With access to very detailed tolerance for the production of a piece of progressively higher production speed of thought as well as strengths. With build tools with high hardness, the conditions for raising production rates are also improved. Until today, using high speed machining techniques with pieces detailed with very short production time in tolerance . To achieve the capability of machining with high speeds you need in various fields such as structural design, its vibrations control excites, find the best rates and motion control chip and speed in order to achieve the desired path to progress

In order to control the movement of a single CNC machines in the path within the Finder. Most of the CNC capability within the Finder only interpolated in the direction of the line and the circle. Because the shape of a curved path for machining in general mode of using this type within the Finder needs to break down the curve to pieces from the line and circle, therefore these two types of interpolated alone meet all uses including high speed machining in 4 ", not". So the use of a different kind from within Finder means interpolated curve a essential in order to appear. Several researchers in this field have been researched and based on the use of different algorithms for polynomial parametric curve in general mode.

CNC machine tool axes in the contract

EIA standard RS-367A related to motion axis in 14 different car types. The number of axes of motion in a conventional tool machines generally, up to five-axis milling machines and up to fourteen axes as well. Machine tool in the coordinate system of the saddle are planning card. The original three-axis motion with y, x, z names are known as the z axis perpendicular to the x and y, a three-axis coordinate system make up the right hand move the positive z axis causes the workpiece away from the cutting tools.  The specified direction in any form represents the positive direction of the axes on each of the machines. Drilling and milling machine on the two axes x, y on the page horizontally. The drilling machine in the positive z axis motion causes the spindle to be going up while the milling on the photo. CNC in just two-axis machining is enough to make the move and because the spindle horizontally aligned the horizontal axis z as well. Also, the letters C, A, B is also for the angular motion of the axes X, Y in the order around, Z.

Building a NC program:

NC machining process of a program is a show piece. The program of the block that contains the information that each block starting with the letter N and the specified line number. For example, a typical block of a program will be able to form NC:

N0040 G91 X25 Y10 Z-12.55 F150 S1100 T06 M03 M07

Each block is composed of several words and any word that starts with a letter, number, then it represents a certain command to the car. Words that start with the letters M, G are thus as preliminary and miscellaneous functions introduction. Types of letters used in numerical control machines can be described as the following summary:

N ............    Program line number

G ............    Basic functions

X ............    Move in the direction of x axis

Y ............    Move in the direction of the y axis

Z ............    Move in the direction of z axis

A ............    The angular momentum axis x

B ............    Angular momentum around the y axis

C ............    Angular momentum around the z axis

F ............    The rate of progress

M ............    Auxiliary functions

S ............    Spindle speed

T ............    Tool number

R ............    Rapid movement z axis

Types of words allowed in the NC and related functions can be found in the ISO1056 standard international

 The classification systems of numerical control

Numerical control systems can be categorized on the basis of the following four groups:

1. According to the type of the car: point to point machining vs. continuous machining.

2-based hardware or NC controller: building in front of the CNC.

3. based on the method of planning: development versus absolute ways.

4. on the basis of the type of the loop control: open loop vs. closed loop.

Point to point machining vs. continuous machining is the simplest example of machine tool NC point-to-point (PTP) for the drilling machine drilling, the workpiece is in line with the axes to move comes up where you will be located in the center of the hole there just below the tools. Then the spindle automatically moves to the side of the workpiece and the drilling operation is done. After the completion of a hole of the desired progress without control of the car and with a quick move to the work piece and move up to a new spot that would have been a repeat hole Grill operation.

In a system of cutting tool path of PTP and the rate of progress when it passes from one point to the next point of importance is not much and the motion path from the point of beginning to need not control endpoints (figure (3-2)). So the system just needs to control the position of the final is at the point where the hole should be in the piece. This is the kind of operation performed by the PTP G00 function [1].

A continuous path such as machining systems in operation milling machine cutting operations while tool gives the axes also moves in the path specific pieces of work. All axes are simultaneously should be able and move with different speeds to create the desired path profiles. Especially when the target is a non-linear path changes the speed of each of the axes is very important.

In continuous systems, position the shear tool at the end of each episode, along with the ratio between the speed of the thrust, the correct path in the desired modal piece machining. Also advancing on the quality of the final level of the region. Because this system error at the speed of a shaft causing error on machining path. The system must have a continuous position control loops as well. CNC machines at each axle is equipped with a separate position control loop and a counter to get the dimension information is the piece that this information, along with the rate of advance of the desired data processing unit to the DPU for appropriate interpolation.

Lathe: a tool for scraping and shaping metal to wooden parts and the rotating work usually goes. Due to the high precision and quality of the production economic CNC machine in different forms formation forms the majority of spare parts has been a circular cross section and are produced with CNC machines and on the other hand in order to low and high speed turning than other methods used car Shaving is a common method used in the industry.

History of CNC machine:

• CNC machines is the most basic type of machines that the application process, the history of it between 17 and 18 century which started at the beginning of the most typical or the oldest method of shaving, shave wood by tree. This means that the two ends of the stick between two trees and put a rope to the tree branches and around it the desired wood complex and the other side of the rope the rope by hand and someone else to move the person's puts the latter of which is located on the opposite side with the wood grate Could this btrashd is the oldest method of cutting wood.

• The first CNC machine was made in France in the year 1740. The main axis of rotation of the device in the car was by hand, a drive shaft (shaft work) directly on the device that is connected to the main shaft by two gear wheels connected to a simple screw Rod Barry is. In this type of machine to switch gears of different screws for different masonry screws had been anticipated.

In 1796 a English name of fidman for the first rank machines shave that Barry was a bolt that holds the rod with the stand-off on the main axis of the gearing and screw axis Berry would have to make a variety of screws for profile.

• In the years 1800 and 1830 USA cars were built with masonry and wooden hull was equipped with iron base. In 1836 the United States in the name of personal panton in Massachusetts car shave with rod screws go. In the year 1853 New York freeland called personal car has 20 feet are Rails with masonry that things could take a 10 inch diameter btrashd coarse ferrous and body construction, it was the position of the gear swap.

• After some time the better machines in terms of power and was made more periods called CNC machines, gear box. These machines have a gear box and load box also is that the car can be easily automated and shave different things.

The most important parts of the controlling and regulating:

Lathe carrier supert carts carts along the front of the device there are longitudinal supert carrier cans that can be used by that device over the longitudinal carrier supert between devices and device.. The main task of these carts set up and put the cutting tool in each episode is desired, before your time to work. Trolleys carts. device by device. it can be driven shift. Rotate it, usually by hand. With rotating trolleys, fixed axis can be fit inside.. right in the forehead which is located rather than the workpiece. In addition, Rotate clockwise OK hours carts also cause the axis (the axis be firmly inside.) go forward towards the workpiece. On the other hand in case of a device within the drill mount axle. while rotating the handle that can be used with front-drive drills, drill or hole in the forehead work.. CNC lathe machine components of four distinct forms: part 1-bless. fixed (1) which is always located in the left side of the worker and containing the axis of the machine.

2. that negahdar animated (2) have been working right and can shift, turning on the table. Can type.. constant motion (3) or (4)..

3.-(1) utility that negahdar controlled lathe tool it can move diagonally or transverse and longitudinal and circular administration.

4. CNC table (2) pieces on the top tried to ride it. The end of the frustum. fixed by pressing your seat on the right at the end of the shaft, prop. Bless d centered at harneh. fixed with three-storey roundabout car are (I) that do not have the circulation of the communication, with the axis of the belt from the motor to your liking or found in tranimision.

And gears (n) on the fuselage-mounted roundabout. Ochrkh gear (m) with the corresponding axis and itching on the outside of the center of the axis parallel to the axis of the gear and put (U) and (t) can be the gear (n) and (m) corresponds to the axis can be fingered by the (O) related to Iran.

Rotational speed with six-axis to this mechanism. The axis of the tube and form D is voided, it centered on the two abutments the body relies on. constant (A) and body regularly installed on lathe table.

Upper supert:

The upper transverse supert supert located on the hand by a manageable and the other is smooth and round tablets page beneath it that its environment between zero to 180 degrees has been graded. With open screws for profile it becomes its supert manual turns 360 degrees revolves around. This device can be a short internal and external the cones and the cones also Shave full, and in the meantime will also use it for Got shave screw on the device ring there is a degree to set exact times about using. Through the if with very little time for payment is needed. Of course, in a rough, razor shave and take a lot of the time it used to be. But in the frustum or long turning most of the automatic method is used

The main axis of the cone change page:

The main axis of the cone on the page change speed gear box speed, which rotate by hand any of the previously defined periods can be achieved. The speed of the machine to the work piece size and type and the type of gear which can be used to determine shave. Generally, the speed of the car after the workpiece and shaving gear located on the machine set up and also the speed of the car by in order to be RPM

Progress value table grate:

To determine the amount of time that is, advancing grate when shaving of gear box that is below the main axis of the gear box is located that includes a pair of gears with the certain ratios would be used for the amount of the advance (bar) ۰٫۰۰۲ up to ۰٫۱۳۰ inches (0.5 to 3.3 mm) are considered the necessary amount of time By category on the shell with its handling.

Effective factors in the choice of the cutting speed:

Several factors affect the cutting speed in the selection have irreplaceable due to improved durability and work tools that will: (a) the work piece material): according to the sex of a workpiece, the cutting speed can be chosen and whatever sex work harder, more difficult to download filings and more heat production Whatever the meaning is the same sex more hard work than less cutting speed can be selected. (B)), the more sex the sex tool: tool is more difficult and can withstand high temperatures to maintain their tolerance, wear more in front, you can choose more quickly. The cutting speed of the tool with a direct relationship to sex. (C) the purpose of the tool durability: durability) tool, is the time when we made with grated sharp chip operation and in the event of being fixed other factors determines the cutting speed, more choices, less tool durability. D) cross section cross section with the increase in filings: chip, high cutting force and more heat on the edge to win. For this reason the cutting speed in the rough work less and do more in pay.

The main task of a CNC machine:

The main task of the CNC machine parts, change in the size, form, finishing with one or more parts with CNC cutting action set grate. With the pickup of the CNC machines and spare devices on the scope of its activities has expanded so much in circumstances that can be done by the various operations, such as inserting tools such as drill and reamer and power because the operating machine on a CNC machine simply do she will ACC O.

The basis of CNC machines:

Generally, the basic principles of CNC machines, based on the action of metal-cutting the base rate and is also made of metal with CNC machines also cause masonry to withdraw by filing the cutting edge gear and motion filings filings over the surface of the grate. In all operations such as turning, drilling, lathing, metal milling machine or saw something chip will be produced. In this case a force equal to 20 tons per square inch can be entered, which is the amount of stretch and change too much force causes a metal form and create the heat and move the friction caused during the cutting surface of the chip and the amount of friction on the cutting edge grate heat generation, which this An important factor is when the download chip

The forces that affect cutting tool:

At the time three different cutting edge power lathe cutting tool will affect these three forces simply expressed as follows.

1. axial force

2. radial force

3. the force of vertical (tangential)

The cutting speed is the factors appropriate for any car:

1. type of grate

2. Type I had shaved (in terms of softness)

3. the amount of depth of chip

4. the type of masonry that can be given (rough or pay something)

5. the age and condition of the car

6. cooling materials (water and oil soluble)

• Cutting machines for software is basically a matter of finding the right speed for each type of machine. Because when the cutting speed too need to be controlled and fast cause the deterioration of the work. The cutting speed is less than the limit caused Kennedy job and as a result of the lack of production of the product will be fast.

The cutting speed value formula:

• Cutting speed according to the meters in diameter in mm min: in the number PI in round numbers divided by 1000

• Cutting speed according to the diameter in feet-per-minute Inch in the number pi divided by 12

D in respect of which (1) the value of the diameter of the work in terms of m and n the number of RPM and the speed of the cut in terms of meters per minute. In respect of (2) D diameter of the work in terms of inches and feet per minute will be determined by round car by diagram

To be on time and efficiency calculation of stop. In most installations the number on the car away from the set diagrams are usually installed on lathe machines more boxes, which is simply the number of different diameters for car remote work.

A variety of CNC machines and buildings that are:

1. small turning Switchblade.

2. CNC machine pulsive

3. a typical soft CNC machine

4. CNC lathe forehead

5. vertical lathe

Small CNC machine folks:

This type of CNC machine CNC for training and used the small tasks, and since most things between the two it went to you. trashand CNC machine. folks say. In addition, because of this machine for training and small things often used it as a transfer device to move a belt grinder are made. In terms of size, are divided into two shapes; a small lathe, small lathe desktops and leggy.

CNC machine tool building

The difference of this type of machines with others is that toolmaking machines have more accurately than other cars, and also some with special devices to shave closer things are equipped. The main task of these machines supplying tools and CNC machines for manufacturing shablan and manufacturing; and because of it for small and large tasks usually used it to two available for desktops and leggy. A type of small parts to CNC desktop and short that has a low diameter are used. CNC machine precision CNC machine as a leggy and relatively big which has different speeds have been made with the precise braking devices to cut and control equipped with speed. This is another means for booking your car is equipped with other tools.

CNC machines have been soft regular

These machines are often used in manufacturing jobs because of its high productive power and also somewhat heavier are made. On the other hand because to do different tasks are used to this in order to have more speed and more steps would be to do great things is very suitable, and also in terms of strength and superiority over other machines can be used for low The production of the.

CNC machines with large diameter and length of deployment

This type of machines for cutting things that are large in diameter and also has large length are used because they are large desk and the height of the main axis of the car up on the rails are relatively high. CNC machines in some that have are too long to be used as the maximum diameter of the main axis, an expert on the rails of a piece has been placed when necessary it can be a separate piece from the rails and then parts with large diameter for lathe and shave Specific tasks can be used. Usually this kind of machines not designed with immense periods, and on the other hand the cutting power and strength is very high, it can be used with more filings in the volume of a given time.

CNC machine CNC forehead:

Things that are relatively high and the length of its diameter a little by these machines are shaved. Other uses in factories making Diesel locomotives for build Diesel locomotives and cyclic as well to make the (flywheel) are used.

Vertical lathe machine

• As the name implies this machine is placed vertically, the pen device stuck in the form of the Charter of the polygon that can be vertically linear motion. The three device system is very large and is placed vertically and has a circular motion, which is to get a heavy duty. At the time of the machine it is

The main components of a CNC machine and each task:

1. Rails (table)

CNC machine types

1. the ordinary lathe

2. CNC machine with CNC control computer

Milling Machine: One of the machine tools and machining These devices are similar in appearance and for drills with the difference that you have at least a three-axis table movement. (x y z)

Winner of this device, the blade of milling tools. Some things that can be done on this machine

• Razor page

• Bring in Groove

• Cutting

• Side shave

• Gear teeth shave

• Spiral gear shave

• Copy of copy of the work by means of milling machine

• Razor blade to form milling form.

Milling machines in General can be divided into two categories:

• General milling machines

• Special milling machines

General milling machines to vertical and horizontal milling machines can be divided into:

Horizontal milling machine

The centerpiece of this type of machine tools horizontal milling and table them in three directions perpendicular to both the longitudinal and the transverse and vertical-move. Machine tools horizontal milling may be simple or for doors angular. Tables for machine tools horizontal milling for doors angular vertical axis in addition to the aforementioned movements away rotates and thus not only in the direction parallel to or perpendicular to the axis of the machine but also along each angle relative to horizontal on the screen it moves. Machine tools horizontal milling straight grooves and surfaces for shaving and razor shave and grate and spiral form to work.

Simple horizontal milling machine main parts: 1-column, 2-axis mechanism the gearbox 3-4 speed gear box-table 5-upper arm 6-jugular 7-page 8-strap knee grate machine

Car column of iron casts and shaped cans and made it inside the motor actuator, gear box mechanisms speed, load and car mechanism are mounted to the jugular.

Lap Desk for car, car is a solid abutment and upper casual way that Ann to move the embedded table. In order to make the work piece vertically so the car lap times showed that on the vertical column formation.

Jugular Central steel and machine is voided that fixed milling on the blades. Speed gear box to change the rotational speed of the jugular (axis) is considered. Gear box once to move the table in three directions to work.

Vertical milling machine

Vertical milling machine building as the photo suggests similar horizontal milling machine set with the difference that its axis is vertical and perpendicular to each other in three directions. Of the vertical milling machines for shaving the edge milling of surfaces by means of their WINS are located on their forehead.

Milling blade types:

Cutting tool on this device are blade-fingered, mercenary, a modular people, roller, swallows

The various operations of the blades of the milling is done pursuant to the variation of the shape and size of these tools. If this on all the other tools that are used machinery is the preference. However the choice of blade milling in most cases is by no means as difficult because the shape and size of that surface must be working and the quality of milling milling operation (rough shave or pay something) the shape and size of the milling. The geometric shape of blade geometric shape milling and edge of the grate is the winner of the original winning one or two minor edge. Milling blade can be divided in terms of the following: (a) to the axis of the gear situation) blade milling: all roller and angular and frontal cone shave. B) gears: all the right gear and spiral gear and gear tilt. (C) domestic building: all simple integrated) and ink and chndparche. D) blade milling close method: all punching and fingered. How to do the work: all e) roller and angular and mercenary CNC lathe and the form of the forehead and the CNC lathe-screw and gear, etc. The milling blade based on the shape and the type of work that they are doing are divided as follows: 1. all roller: roller with all the right gear or on the lateral surface of a cylindrical Helix is located for scraping surfaces always goes to work. Nowadays all roller with gear-spiral.

Edge wins this shank cutters work goes down configurations and the resulting calmer milling blade works and thereby further the level of shaved and smooth. In addition to guiding the chip in this shank cutters are better done because your gear milling is also pushing chip can help. Because the number of spiral milling gear that NLP works units together much of the gear is all right it can be a number of cassette and its gear as a result of them coarse ribs than the right gear is the diameter of the milling gear they construct and thus also on the strength of the Gear milling added and also the distance between gears to filings higher guidance. Nowadays all the right gear just to shave 35 mm width levels. The angle of the inclined spiral gear for all fine gear for about 20-25 and for all coarse gear at about 50 to 55 degrees is selected. All spiral gear defect is that when working with axial pressure milling. The value of this pressure to the angle of inclination depend on gears. Because of this, sometimes the two blade spiral milling gear that they opposed each other in order to tend gear (one right and one left) is equal to the angle of inclination, but they can understand the pressure on the milling machine to pivot on the neutral axis and Arbor. 2-all mercenary: the shank cutters for bringing in different slots and cut metals and other things to do. Groove milling gear shave time from the front and both parties work to trashand i.e. the lateral surface of the main action of milling milling do forehead and gives it a smooth Groove wall and pay. All the mercenary for bringing in nicks (the socket slot, etc) and cut the metal process and sometimes also called a saw all. By means of the blade shank cutters can be such a gap width of 3.0-4 mm on the metals. All roller and two large foliaceous fabric often means the body formation of typical steel milling and tool steels from the blades or made tendber together. 3-fingered all conical shaft end cutters: these have or that are cylindrical CAP or by means of special cartridge in the hole axis milling machine are tight. This shank cutters for narrow slots to shave different shapes are used.

Milling blade: this blade are negative are the gear and gear-shaped disk of filings.

Milling blade problems:

1) low accuracy 2) low flexibility to produce different gears 3) create wear and slippage between gears 4) surface fatigue and resonance phenomenon of Pitting 5) the possibility of breaking the blade at high speeds and create serious damage (even death)
