Places workpiece in fixture or positions it on machine table, and secures it with clamps. Mounts cutting tools in spindles. Positions and secures specified drilling jig and moves controls and positions spindles to align tools with guide bushings in jig. Sets stops to control depth of cut. Moves controls to set cutting speeds and feed rates, and regulate flow of coolant. Engages power feed and observes machine operation. Periodically verifies conformance of machined work to specifications, using such measuring instruments as calipers, micrometers, and fixed gauges. May machine plastics or other nonmetallic materials.
