Milling and Planing Machine Setters, Operators, and Tenders, Metal and Plastic

Tasks

Core Tasks Include:

• Remove workpieces from machines, and check to ensure that they conform to specifications, using measuring instruments such as microscopes, gauges, calipers, and micrometers.
• Observe milling or planing machine operation, and adjust controls to ensure conformance with specified tolerances.
• Position and secure workpieces on machines, using holding devices, measuring instruments, hand tools, and hoists.
• 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, and to start machines.
• Compute dimensions, tolerances, and angles of workpieces or machines according to specifications and knowledge of metal properties and shop mathematics.
• Verify alignment of workpieces on machines, using measuring instruments such as rules, gauges, or calipers.
• Select cutting speeds, feed rates, and depths of cuts, applying knowledge of metal properties and shop mathematics.
• Move cutters or material manually or by turning handwheels, or engage automatic feeding mechanisms to mill workpieces to specifications.
• Replace worn tools, using hand tools, and sharpen dull tools, using bench grinders.
• Select and install cutting tools and other accessories according to specifications, using hand tools or power tools.
• Record production output.
• Turn valves or pull levers to start and regulate the flow of coolant or lubricant to work areas.
• Mount attachments and tools, such as pantographs, engravers, or routers, to perform other operations, such as drilling or boring.

Supplemental Tasks Include:

• Make templates or cutting tools.
