Conduct test runs with completed tools or dies to ensure that parts meet specifications; make adjustments as necessary
Cut, shape, and trim blanks or blocks to specified lengths or shapes, using power saws, power shears, rules, and hand tools
File, grind, shim, and adjust different parts to properly fit them together
Fit and assemble parts to make, repair, or modify dies, jigs, gauges, and tools, using machine tools and hand tools
Inspect finished dies for smoothness, contour conformity, and defects
Lift, position, and secure machined parts on surface plates or worktables, using hoists, vises, v-blocks, or angle plates
Measure, mark, and scribe metal or plastic stock to lay out machining, using instruments such as protractors, micrometers, scribes, and ruler
Select metals to be used from metals and alloys, based on properties such as hardness and heat tolerance
Set up and operate conventional 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 in parts for assembly
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
Cast plastic tools or parts, or tungsten-carbide cutting tips, using pre-made molds
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, feed or place parts, tools, or assemblies into furnaces to harden
