Metal and Plastic Model Makers

<ul><li>Study blueprints, drawings, and sketches to determine material dimensions, required equipment, and operations sequences.</li><li>Inspect and test products to verify conformance to specifications, using precision measuring instruments or circuit testers.</li><li>Drill, countersink, and ream holes in parts and assemblies for bolts, screws, and other fasteners, using power tools.</li><li>Set up and operate machines, such as lathes, drill presses, punch presses, or bandsaws, to fabricate prototypes or models.</li><li>Cut, shape, and form metal parts, using lathes, power saws, snips, power brakes and shears, files, and mallets.</li><li>Devise and construct tools, dies, molds, jigs, and fixtures, or modify existing tools and equipment.</li><li>Grind, file, and sand parts to finished dimensions.</li><li>Rework or alter component model or parts as required to ensure that products meet standards.</li><li>Program computer numerical control (CNC) machines to fabricate model parts.</li><li>Lay out and mark reference points and dimensions on materials, using measuring instruments and drawing or scribing tools.</li><li>Align, fit, and join parts, using bolts and screws or by welding or gluing.</li><li>Consult and confer with engineering personnel to discuss developmental problems and to recommend product modifications.</li><li>Assemble mechanical, electrical, and electronic components into models or prototypes, using hand tools, power tools, and fabricating machines.</li><li>Use computer-aided design (CAD) and computer-aided manufacture (CAM) software or hardware to fabricate model parts.</li><li>Record specifications, production operations, and final dimensions of models for use in establishing operating standards and procedures.</li></ul>
