The Prototype Machinist sets up and operates conventional, special purpose and numerical control (CNC) machines and machining centers to fabricate metallic and nonmetallic prototype parts by evaluating machinability, designs and builds special tooling in order to effectively produce parts to specification.
ESSENTIAL DUTIES AND RESPONSIBILITIES:
Studies blueprints, sketches, drawings, manuals, specifications, or sample part to determine dimensions and tolerances of finished workpiece, sequence of operations, and setup requirements.
Measures, marks, and scribes dimensions and reference points on material or workpiece as guides for subsequent machining.
Selects, aligns, and secures holding fixtures, cutting tools, attachments, accessories, and materials on machines such as mills, lathes, jig borers, grinders, and shapers.
Calculates and sets controls to regulate machining factors such as speed, feed, coolant flow, and depth and angle of cut, or enters commands to retrieve, input, or edit computerized machine control media.
Verifies conformance of finished workpiece to specifications.
Sets up and operates machine on trial run to verify accuracy of machine settings or programmed control data.
Should demonstrate a proficiency in the set up and operation of all types of conventional and CNC Mills and Lathes. Experienced in the use of surface grinders, drill presses, tool cutter grinders and saws (Horizontal/Vertical). Ability to read and interpret blueprint drawings. Ability to use precision measuring and gauging instruments while performing required inspection on parts being machined or fabricated.
