Tasks for Machinists
- Studies sample parts, blueprints, drawings, and engineering information to determine methods and sequence of operations to fabricate product.
- Assembles parts into completed units, using jigs, fixtures, hand tools, and power tools.
- Calculates and sets controls to regulate machining, or enters commands to retrieve, input, or edit computerized machine control media.
- Measures, examines, and tests completed units to detect defects and ensure conformance to specifications.
- Operates brazing, heat-treating, and welding equipment to cut, solder, and braze metal.
- Cleans, lubricates, and maintains machines, tools, and equipment to remove grease, rust, stains, and foreign matter.
- Cuts and shapes sheet metal and heats and bends metal to specified shape.
- Observes and listens to operating machines or equipment to diagnose machine malfunction and determine need for adjustment or repair.
- Evaluates experimental procedures and recommends changes or modifications for efficiency and adaptability to setup and production.
- Tests experimental models under simulated operating conditions for such purposes as development, standardization, and feasibility of design.
- Designs fixtures, tooling, and experimental parts to meet special engineering needs.
- Confers with engineering, supervisory, and manufacturing personnel to exchange technical information.
- Establishes work procedures for fabricating new structural products, using variety of metalworking machines.
- Installs experimental parts and assemblies, such as hydraulic systems, electrical wiring, lubricants, and batteries into machines and mechanisms.
- Dismantles machine or equipment, using hand tools and power tools, to examine parts for defect or to remove defective parts.
- Installs repaired part into equipment and operates equipment to verify operational efficiency.
- Lays out and verifies dimensions of parts, using precision measuring and marking instruments and knowledge of trigonometry.
- Fabricates, assembles, and modifies tooling, such as jigs, fixtures, templates, and molds or dies to produce parts and assemblies.
- Operates metalworking machine tools, such as lathe, milling machine, shaper, or grinder to machine parts to specifications.
- Selects, aligns, and secures holding fixtures, cutting tools, attachments, accessories, and materials onto machines.
