Turning is one of the
oldest and the most fundamental manufacturing processes. It is the
machining of a round workpiece; the profile of the workpiece can
be straight, conical, curved, or grooves, like shafts, spindles,
pins, handles, and various machine components. In turning, the work
piece is rotated and the cutting tool is stationary; this is different
from another very old and traditional machining process, milling,
where the cutting tool rotates and the workpiece moves in transition
of a turning operation showing depth of cut, d, and feed, f.
Cutting speed is the
surface speed of the workpiece at the tool tip.
