• Setup and remove workpieces from machines and check to ensure that they conform to specifications, using measuring instruments such as gauges, calipers, and micrometers.
• Observe machine operation and adjust controls to ensure conformance with specified tolerances.
• Study blueprints, layouts, sketches, or work orders to assess workpiece specifications and to determine tooling instructions, tools and materials needed, and sequences of operations.
• Move controls to set cutting specifications, to position cutting tools and workpieces in relation to each other.
