Multiple Machine Tool Setters, Operators, and Tenders, Metal and Plastic

Tasks

Core Tasks Include:

Inspect workpieces for defects, and measure workpieces to determine accuracy of machine operation, using rules, templates, or other measuring instruments.
Observe machine operation to detect workpiece defects or machine malfunctions, adjusting machines as necessary.
Read blueprints or job orders to determine product specifications and tooling instructions and to plan operational sequences.
Set up and operate machines, such as lathes, cutters, shears, borers, millers, grinders, presses, drills, or auxiliary machines, to make metallic and plastic workpieces.
Position, adjust, and secure stock material or workpieces against stops, on arbors, or in chucks, fixtures, or automatic feeding mechanisms, manually or using hoists.
Select, install, and adjust alignment of drills, cutters, dies, guides, and holding devices, using templates, measuring instruments, and hand tools.
Change worn machine accessories, such as cutting tools or brushes, using hand tools.
Make minor electrical and mechanical repairs and adjustments to machines and notify supervisors when major service is required.
Start machines and turn handwheels or valves to engage feeding, cooling, and lubricating mechanisms.
Perform minor machine maintenance, such as oiling or cleaning machines, dies, or workpieces, or adding coolant to machine reservoirs.
Select the proper coolants and lubricants and start their flow.
Remove burrs, sharp edges, rust, or scale from workpieces, using files, hand grinders, wire brushes, or power tools.
Instruct other workers in machine set-up and operation.
Record operational data, such as pressure readings, lengths of strokes, feed rates, or speeds.
Extract or lift jammed pieces from machines, using fingers, wire hooks, or lift bars.
Set machine stops or guides to specified lengths as indicated by scales, rules, or templates.
Move controls or mount gears, cams, or templates in machines to set feed rates and cutting speeds, depths, and angles.
Compute data, such as gear dimensions or machine settings, applying knowledge of shop mathematics.

Supplemental Tasks Include:

Align layout marks with dies or blades.
Measure and mark reference points and cutting lines on workpieces, using traced templates, compasses, and rules.
Write programs for computer numerical control (CNC) machines to cut metal and plastic materials.
