Secures specified tool in spindle. Lifts workpiece manually or with hoist, places it in fixture or jig or on machine table, and secures it with clamps or holds it in position under spindle. Moves controls to set cutting speed, feed rate, and depth of cut. Engages power or automatic feed or manually operates feed lever to feed tool to specified depth in workpiece. Turns valve handle to start flow of coolant against tool and workpiece or dips tool in cutting oil prior to mounting. Verifies conformance of machined workpieces to specifications, using such measuring instruments as calipers, micrometers, and fixed gauges. May position and secure drilling jig to guide cutting tool.
