Cutting tool on the workpiece. Foam cutting tool the workpiece. Cutting tool into the workpiece.
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.
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.
Reference points: Think about how the part will be made, and how it will be inspected. Usually something will make sense. Try to keep common references between drawing views, and if possible try to base everything from points, planes, or edges that appear in multiple views. Tolerances: Consider how the part will be made- what minimum tolerances can be held on the intended equipment and processes? What is the maximum tolerance on the individual parts that will allow the assembly to fit together and function properly? The right answers lie between those extremes.
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.
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.
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
depending on machine-x and z zero machine reference points are in the upper right hand corner(away from workpiece) whereas your programmable origin point used for your specific program is completely up to you.

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.

I can interpret this passage. Would you interpret that answer for me?
What is the angle of a workpiece if a 3.2003 gage block stack is used with a 10 sine bar?

For various reasons. Not adjust the milling machine. Sudden collision with the workpiece. Hard sex of the workpiece. High heat during cutting.
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.
These are the basic steps to align a work piece in a four-jaw chuck.Make sure the machine is turned off and in the spindle in neutralMeasure the diameter of the workpiece where you wish to clamp it (inside or outside). For this example we will use the outside diameter.Using the grooved lines on the face of the chuck, align the inside of the jaws to a line close to the diameter measured from the workpiece.Measure the inside of the jaws (gripping surface) and set the jaws closer, one-by-one from opposite sides, to the workpiece diameter.Insert the workpiece in the chuck and close the jaws again, one-by-one and bit-by-bit, until the workpiece is secure.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 workpieceSet a magnetic base dial indicator on the bed of the lathe so the sensor button touches the workpiece.Align jaw 1 up with the dial indicator and note the setting.Spin the chuck by hand to jaw 3. If the dial indicator reading increases, tighten jaw 3. If it decreases, tighten jaw 1. Repeat the process until it is close, but not perfect. It may be required to slightly loosen the opposite jaw to achieve the required amount of movement. Do not over-tighten.Repeat the process between jaw 2 and jaw 4.When the workpiece is close to being aligned, fine adjustments can now be done by tightening and slightly loosening (if necessary) the opposite jaws until the dial indicator is within 0.01mm or 0.001in.Go around every jaw and tighten as required until workpiece is safely secured. Care must be taken not to distort the shape of softer or hollow components due to its structure or material hardness. Eliminating jaw marks on the workpiece can be achieved by using strips of 1mm shim stock between every jaw and the workpiece.Steps B: Rough or un-machined diameter workpieceSet a surface gauge on the bed of the lathe then align jaw 1 up with the needle point so the needle is 2mm or 3mm the workpiece.Spin the chuck by hand to jaw 3. If a the gap between the needle and workpiece increases, tighten jaw 1. If it decreases, tighten jaw 3. Repeat the process until it is close, but not perfect. It may be required to slightly loosen the opposite jaw to achieve the required amount of movement.The surface gauge can be moved closer to the workpiece the closer the alignment gets. Do not over-tighten the workpiece.Repeat the process between jaw 2 and jaw 4.When the workpiece is close to being aligned, fine adjustments can now be done by tightening and slightly loosening (if necessary) the opposite jaws until the needle constantly touched the surface of the workpiece all around.Go around every jaw and tighten as required until workpiece is safely secured. Care must be taken not to distort the shape of softer or hollow components due to its structure.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!
make easy to loading and unloading operation, that's why you need the gap between the coil and the workpiece
During the facing process of a workpiece over its entire face, the center is not required and is not set into the workpiece, therefore no forces are present on the center.
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.
The package is part of the workpiece.
