a laithe works by a rotating jaw with ur work in the chuck and u can use many laithe tools to cut difrent things off of your work sick bled dont mention
It has a head stock(fixed and is connected to motor) and a tail stock(movable).The tool is moved towards the workpiece (which is driven by motor).Used for making cylindrical sections,tapering,drilling..
A CNC lathe is basically the same as a conventional lathe. The major differences are:
The material to be machined into a component along with the drawing of the component is evaluated and a program is written on a computer for machining the component in various steps with the different required tooling.
Once the program is done, it is transferred to the CNC. The program can be directly programmed into the CNC too. Tooling is then selected, mounted and set into the CNC's database so the machine knows exactly where the tip of the tool is in relation to the workpiece.
The CNC is then run without the workpiece and watched by the Setter to ensure there are no irregularities during the machining process. When all is ready and the settings are done, the setter would place the material into the chuck and clamp it.
The machining cycle is started and the setter would do it in steps on the first component in order to adjust some tooling stopping distances, feeds, coolant on/off and tooling offsets.
Once the first component is finished, the production cycle is started. The operator then puts the material into the machine and pushes the start button and will remove the completed component without human interference. The components are often checked for accuracy and adjustments are made when necessary.
The program of a CNC composes of sets of commands that tells the machine what-, when-, how fast-, and with what tooling to do a certain operation. Also What should be turned on or off at the time.
These commands control relays, servo motors, solenoids, hydraulic valves, etc to achieve the multiple operations of the machine.
The three basic operations that can be performed on both a metal or wood lathe machine are turning, boring and facing. At least one--if not all three--of these functions will be used each time you work on a project. The only things that will change are the tools used and the speed and feed of the lathe.
These are the basic steps to align a work piece in a four-jaw chuck.
If it is a machined diameter workpiece, further follow steps A.
For a rough or un-machined diameter workpiece surface, further follow steps B.
Steps A: Machined surface workpiece
Steps B: Rough or un-machined diameter workpiece
The above method is just a basic explanation of how the operation is achieved. Operating a lathe without proper training is not recommended and could lead to serious injury!
A lathe holds its workpiece by means of a chuck. A chuck has three or four self-centering or four independent jaws which clamp the workpiece.
Milling in a lathe can be two things:A cutter is gripped in the chuck and a workpiece the the tool post. The work piece is then milled by using the feed on the lathe. Although it has been done, it is an unconventional method and is not recommended.A 3-in-1 lathe with a milling attachment as part of the machine used for milling a work piece.
Chuck, Collet, Faceplate, between centers
A milling machine basically look like a drill press, but with the ability to move the work piece sideways. A lathe clamp and spin the work piece horizontally and use a stationary tool bit to cut and shape the work piece.
In auto lathe machine, All the processes is automatic from the beginning to the end . Machine take working pieces from the workpiece box where all the pieces loaded initially,then all the processes done on the workpieces as per the command is given initially . final product comes out finally. But in semi lathe machine , all the work is same as automatic lathe but feed is not automatic it done by manually by technician .
Although the planer and shaper are able to machine flat surfaces,there is not much overlapping in their fields of usefulness. They differ widely in construction and in the method of operation. When two machines are compared the following differences may be seen:1. The planer is especially adapted to large work; the shaper can do only small work.2. On the planer the work is moved against a stingray tool; on the shaper the tool moves across the work which is stationary.3. On the planer the tool is fed into the work; on the shaper the work is usually fed across the tool.

it is basically used for machining..
The ones that i use at college and work are a milling machine, a lathe, a drill, and a saw but i think the main ones (In mechanical engineering) are the Milling Machine and the Lathe.
Lathe for making the cross piece is rounded. The tool is a piece of stationary spins. Milling machines for making flat pieces. The tool rotates the piece is stationary. +++ "Planing" in machine-tool terms describes the action of a Planing-machine, which moves the workpiece held on a horizontal table against a cutting-tool held on a frame adjustable for height (cutting depth) and cross-feed. Not often used now, having largely been supplanted by the milling-machine, and for very large work the plano-mill. ' The planning-tool itself resembles a chisel ground to particular angles.
There are various ways for a lathe to hold its workpiece.The workpiece could be held between centers from the spindle and tail stockIt could be gripped in a chuckA faceplate could be used and the workpiece is screwed, bolted or clamped to it.
One advantage of a lathe machine is that it can perform very detailed and intricate designs. One disadvantage of a lathe machine is that these machines are more expensive than other types of machines used to produce this type of work.

A cnc lathe can manufacture nearly anything cylindrical. Some even have attachments to do other types of work in the machine as well, for a virtually endless array of parts. Whatever you can imagine really, as long as it will fit in the machine.
The work piece is tight hold in the chuck. the chuck part of the lathe machine .it is made of mild steel .clamping to hold the device to normal cutting and simple .clamp the workpiece rigidly. no vobration of the work piece as well as cutting tool . prevent breakage of the cutting tool. physical accidents can be avoided
