Position and secure workpieces on machines, using holding devices, measuring instruments, hand tools, and hoists.
Remove workpieces from machines, and check to ensure that they conform to specifications, using measuring instruments such as microscopes, gauges, calipers, and micrometers.
Verify alignment of workpieces on machines, using measuring instruments, such as rules, gauges, or calipers.
Move cutters or material manually or by turning handwheels, or engage automatic feeding mechanisms to mill workpieces to specifications.
Observe milling or planing machine operation and adjust controls to ensure conformance with specified tolerances.
Select cutting speeds, feed rates, and depths of cuts, applying knowledge of metal properties and shop mathematics.
Study blueprints, layouts, sketches, or work orders to assess workpiece specifications and to determine tooling instructions, tools and materials needed, and sequences of operations.
Compute dimensions, tolerances, and angles of workpieces or machines, according to specifications and knowledge of metal properties and shop mathematics.
Move controls to set cutting specifications, to position cutting tools and workpieces in relation to each other, and to start machines.
Replace worn tools, using hand tools, and sharpen dull tools, using bench grinders.
