Analyzes specifications, lays out metal stock, sets up and operates machine tools, and fits and assembles parts to make and repair dies, cutting tools, jigs, fixtures, gauges, and machinists' hand tools.
This career is part of the Manufacturing cluster Production pathway.
A person in this career:
- Verifies dimensions, alignments, and clearances of finished parts for conformance to specifications, using measuring instruments such as calipers, gauge blocks, micrometers, or dial indicators.
- Sets up and operates conventional or computer numerically controlled machine tools such as lathes, milling machines, or grinders to cut, bore, grind, or otherwise shape parts to prescribed dimensions and finishes.
- Studies blueprints, sketches, models, or specifications to plan sequences of operations for fabricating tools, dies, or assemblies.
- Visualizes and computes dimensions, sizes, shapes, and tolerances of assemblies, based on specifications.
- Inspects finished dies for smoothness, contour conformity, and defects.
- Fits and assembles parts to make, repair, or modify dies, jigs, gauges, and tools, using machine tools and hand tools.
- Conducts test runs with completed tools or dies to ensure that parts meet specifications, making adjustments as necessary.
- Selects metals to be used from a range of metals and alloys, based on properties such as hardness or heat tolerance.
- Files, grinds, shims, and adjusts different parts to properly fit them together.
- Lifts, positions, and secures machined parts on surface plates or worktables, using hoists, vises, v-blocks, or angle plates.
