Duties

• Performs all types of machining operations to manufacture, modify, and repair aircraft parts, support equipment, tools, and assemblies. Fabricates local manufactured items required for aircraft components. Work includes bending, cutting, forming, casting, cleaning, molding, welding, sawing, machining, and assembling. Lays out work, reads and interprets blueprints and technical publications, designs and draws working sketches, makes special tools, dies, jigs, and fixtures, performs production work of aircraft parts, and works to tolerances varying from.0l0 to .0005 inch. Troubleshoots difficult metal machining designs and fabrication problems. Plans work, taking into consideration the type and numbers of machining/welding operations, machines to be used, and type of set-ups and methods of production such as cutting, milling, grinding, welding, and polishing. Performs shop calculations such as determination of peripheral cutting speeds and settings. Determines metal identity and characteristics by subjecting metals to spark, acid, fire, magnetic, alkaline, heat, quench, and fracture tests. Tests specimens for predetermined requirements of tensile, bend, shear, and impact strength using materials testing machines. Welds ferrous and non-ferrous metals and alloys such as cobalt, chrome, nickel, aluminum, magnesium, and titanium. Welds butt, lap, tee, and corner joints in flat, vertical, horizontal, and overhead working positions. Welds metals and alloys by shielded gas welding (Heli-arc), metallic arc, oxyacetylene, and resistance welding processes. Heat treats metal parts as required. Compares machine parts with drawings, technical orders, or specifications for conformance with established tolerances, fits, and surface finish. Makes precision measurements using micrometer, vernier calipers, dial indicators, and gauges at various dimensions. Inspects tapered surfaces for variations by applying bearing blue and using surface plate. Determines reparability of damaged machine parts, tools, and aircraft components. Tests metals using Rockwell or Brinell hardness testing methods. Conducts training of drill status guard (DSG) members assigned to the shop. Prepares for and participates in various types of readiness evaluations and inspections, mobility, and command support exercises. May be required to perform such additional duties as structural fire fighting, aircraft fire/crash/rescue duty, security guard, snow removal, munitions loading and handling, heavy equipment operator, maintenance of facilities and equipment, or serve as a member of a team to cope with natural disasters or civil emergencies. May be required to be aircraft welder certified. Performs other duties as assigned.
