Question: A turning operation is to be performed on an NC lathe. Cutting speed = 2.5 m/s, feed = 0.2 mm/rev, and depth = 4.0 mm.

A turning operation is to be performed on an NC lathe. Cutting speed = 2.5 m/s, feed = 0.2 mm/rev, and depth = 4.0 mm. Work piece diameter = 100 mm and its length = 400 mm. Determine
(a) Rotational speed of the work bar,
(b) Feed rate,
(c) Metal removal rate, and
(d) Time to travel from one end of the part to the other.
