Observes operation and indexes turret between operations. Verifies conformance of machined workpieces to specifications, using micrometers, calipers, and fixed gauges. Turns valve and directs flow of coolant against tool and workpiece. May compute such data as dimensions, rotation speeds, feed rates, and machining times, using knowledge of shop mathematics and metal properties. May work on nonmetallic materials, such as plastics.
