A lathe is a machining tool primarily used for shaping wood or metal. It operates by having the
workpiece revolve around a cutting tool that is fixed. The primary function is to remove the
material's undesirable portions, leaving behind a nicely shaped workpiece.
2. What is the operation of lathe machine?

Different operations on a lathe are produced by varying tool ends and a kinematic relationship
between the tool and workpiece. Turning, facing, grooving, parting, threading, drilling, boring,
knurling, and tapping are the most popular lathe operations.
