A workpiece is an unfinished part that is to be shaped some way. And unless you want to hold it in your hands, it has to be clamped, or attached by something like a vise or a chuck before it can be cut or shaped.

What is the working principle of rolling mill machine?
The workpiece is holding on the worktable of the machine. The table movement controls the feed of workpiece against the rotating cutter. The cutter is mounted on a spindle or arbor and revolves at high speed. Except for rotation the cutter has no other motion. As the workpiece advances, the cutter teeth remove the metal from the surface of workpiece and the desired shape is produced.
What does wpc mean in a cnc mazatrol language?
WPC stand for workpiece offsets that means the distance travel tool and workpiece for machining form where se start and how the tool perform in machining
What is the mold clamping force for polyethylene?
You need to know the injection pressure and mold volume to determine clamping force. Material is well im-material to the question at hand.
What is prismatic machining?
a machining process carried out on a workpiece with constant cross-section.
What is a vtl machinist?
this is a vertical turret lathe you stand the workpiece on a horizontal chuck
What is the effect of clamping the workpiece and how can this cause distortion in the finished components?
This can happen when clamps are applied inexpertly and too tightly.
What are the effects of clamping the workpiece in a chuck or work holding device?
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
What are the accessories used for on the center lathe?
Accessories used on a center lathe are:3 and 4 Jaw chuck - Clamping the workpieceChuck spanner - For tightening the workpiece in the chuckSteady - Stabilizing a long workpieceTraveling steady - Stabilizing a workpiece close to the cutting areaCenter, dead center, pipe or rolling center - Centralizes and stabilizes the end of the workpiece from the tail stockCutting tools - Used for cutting or machining the workpieceWrench set (Supplied with the machine) - For setting the gears at the rear of the headstock for specialized operations and machine maintenanceManual oil pump - For lubrication of the machine
What is the principle of clamping in jigs and fixtures?
clamp is a holding device. The principle of clamping is " the clamping forceshouldbe strong enough to withstand forces that are caused during machining and clamping force should not be such high that it will damage the work piece".
What is a vee used for on the Vee Block?
Vee clock is a kind of equipment used to hold circular workpieces. By clamping the the workpiece on it we can finder centre of the workpiece very easily as jt has a right angle slot in it. It can be also used for check the roundness of a circular job using a dial indicator.
What is the difference between grinding and turning?
When grinding, an abrasive material such as carborundum is used to remove material from the workpiece. When turning, material is removed from the workpiece with a cutting tool. The worpiece is usually clamped in the jaws of a chuck, and the chuck turns. the tool is clamped to a toolpost and moved along the workpiece and into the workpiece in order to cut material off in a measured amount.
Why is car clamping good?
It isn't!
Why is it necessary that the tool be clamped tightly in the tool post?
If the cutting tool is not tightly clamped in the tool post it could move when a cut is taken. This can result in the tool penetrating the workpiece as the cut progresses causing an undersized workpiece. It can also eventually bite into the workpiece and possibly cause damage to the workpiece, the lathe, the cutting tool and even injury to the machinist and others in close proximity.

What are the functions of gear train on a lathe machine?
All gearboxes work the same way: there is a gear on the motor, a gear on the thing you're trying to drive, and sometimes a set of gears between the two. The ratio between the gears, plus the RPM of the motor, determines the speed of the workpiece. If the gear on the motor is larger than the gear on the workpiece the RPM of the workpiece will be higher than the speed of the motor. If the workpiece's gear is larger, the workpiece will turn slower than the motor. Given that, though, I've never seen a gearbox on a wood lathe. Wood lathes use belt drive for two reasons, the most important being safety--if you get a catch, a workpiece on a belt driven lathe won't damage you as badly as a workpiece on a gear-driven lathe. Also, belt drive won't feed vibration from the workpiece back into the motor and damage the bearings. Gear drive is used on metal lathes.
What is diode clamping?
There are a couple types of diode clamping-- A P-N diode was often used for clamping coils of relays that produce high voltages when the relays is de-energized. Bidirectional zeners are now the best solution. Diode clamping is also a term used to limit voltage excursions generally. Zener diodes are generally used for this purpose.
When riding a horse is clamping good?
NOOOO!
