Set up and operate conventional (manual) or computer numerically controlled machine tools such as lathes, milling machines, and grinders to cut, bore, grind, or otherwise shape parts to prescribed dimensions and finishes.
Set up and operate drill presses to drill and tap holes as needed for tool fabrication.
Smooth and polish flat and contoured surfaces of parts or tools, using scrapers, abrasive stones, files, emery cloths, or power grinders.
Study blueprints, sketches, models, or specifications to plan sequences of operations for fabricating tools, dies, or assemblies.
Verify dimensions, alignments, and clearances of finished parts for conformance to specifications, using measuring instruments such as calipers, gauge blocks, micrometers, and dial indicators.
Visualize and compute dimensions, sizes, shapes, and tolerances of assemblies, based on specifications.
Sharpen or form grind tungsten-carbide machine cutting tools or inserts.
Design jigs, fixtures, and templates for use as work aids in the fabrication of parts or products.
Develop and design new tools and dies, using computer-aided design software.
Set pyrometer controls of heat-treating furnaces, and feed or place parts, tools, or assemblies into furnaces to harden.
Positions and secures parts on surface plate or worktable, using devices for example vises, V-blocks, and angle plates. Fits and assembles parts into assemblies or mechanisms, using hand tools.
Develops specifications from general descriptions and draws or sketches tool to be fabricated, using drafting tools
