The Machinist supports Air Force test, evaluation, and operational missions by performing precision machining, fabrication, modification, and repair of parts, tools, fixtures, and components in a secure machine shop environment. This position applies advanced knowledge of conventional and specialized machine tools, materials, and machining processes to produce high-quality components to exact specifications and close tolerances. The role requires the ability to interpret complex technical data, plan and execute machining operations, and adapt to evolving manufacturing technologies while supporting mission-critical aerospace and instrumentation requirements at Nellis Air Force Base.
Roles and Responsibilities
• Operate and maintain a wide range of conventional machine tools, including lathes; vertical and horizontal boring mills; bench, plain, and universal milling machines; shapers; planers; internal and external grinders; thread cutters; radial drills; cutting saws; power hacksaws; screw machines; drill presses; and related shop equipment.
• Apply knowledge of the physical properties of metals, metal alloys, plastics, rubber, and other materials to determine suitability for specific applications and to account for the effects of hardening, annealing, and stress relieving processes.
• Plan, lay out, machine, assemble, and hand finish parts to precise dimensions and close tolerances.
• Adapt, set up, and operate conventional and specialized machine tools and attachments, including jig borers, jig grinders, internal and external thread grinders, and electrical discharge machines, as required.
• Devise and construct fixtures and holding devices to support special or complex machining operations.
• Read, interpret, and work from complex blueprints, multi-view mechanical drawings, sketches, and specifications, or prepare sketches from oral or written instructions.
• Apply advanced shop mathematics, including plane geometry, trigonometry, and toolmaker handbook formulas, to establish dimensions and layouts.
• Select appropriate grinding wheels by grit type, grit size, bond, and diameter, and calculate correct surface speeds based on material and machining requirements.
• Use precision measuring instruments and inspection equipment such as micrometers, vernier calipers, height gages, dial indicators, gage blocks, sine bars, optical and electrical comparators, and related devices.
• Verify the accuracy of tools, jigs, fixtures, and gages, and fabricate, repair, modify, and calibrate precision measuring instruments used in the machine shop.
• Maintain awareness of evolving machine shop practices, processes, and technological advancements and apply them as appropriate to manufacturing procedures.
