Operations commonly performed on a lathe include turning, facing, form turning, grooving, drilling,boring, knurling, taper turning and thread cutting. It is used for parts,that must be dissembled for during operations of a machine. Similarly, cam-operated screw machines and chuckers did not disappear; they simply shifted to a different niche. Fit is defined as the degree of freedom of tightness between the mating parts in an assembly process. Lathe accessories include centres, catch plates and carriers, chucks, face plates, angle plates,mandrels, and rests. The first turret lathe was invented by Stephen Fitch in Example of Slide fit :.

The work piece is supported between centres or in any other work holding device, and rotated at the desired speed. The workplace is held between centres or attached to the face plate. Thus the duties of the operator, which were already greatly reduced by the manual turret lathe, were even further reduced, and productivity increased.
In this way, a sequence of operations can be performed on a part without switching tools with each operation.
No cutting is involved in the knurling process.

The latter is due to the toolpath's being controlled by the machine, either in jig -like fashion, via the mechanical limits placed on it by the turret's slide and stops, or via electronically -directed servomechanisms for computer numerical control lathes.
