CNC Operator Milling and Turning
Adjust machine controls and change tool settings to keep dimensions within specified tolerances. Replace worn tools, and sharpen dull cutting tools and dies, using hand tools, bench grinders or cutter-grinding machines. Remove and inspect workpieces to verify conformance with specifications, using instruments such as microscopes, gauges, calipers, micrometers, and dial indicators. Verify alignment of workpieces on machines, using measuring instruments. Observe milling or planing machine operation and adjust controls to ensure conformance with specified tolerances. Start lathe or turning machines and observe operations to ensure that specifications are met. Position, secure, and align cutting tools in tool holders on machines, using hand tools, and verify their positions with measuring instruments. Position and secure workpieces on machines, using holding devices, measuring instruments, hand tools, and hoists. Crank machines through cycles, stopping to adjust tool positions and machine controls to ensure specified timing, clearances, and tolerances. Study blueprints, layouts, sketches or charts, and job orders for information on specifications and tooling instructions, and to determine material requirements and operational sequences. Select and install cutting tools, other accessories and tooling instructions, using hand tools or power tools, according to written specifications or knowledge of metal properties and shop mathematics. Move controls to set cutting specifications, speeds, depths and feed rates, to position tools and work pieces in relation to each other and to start machines, while applying knowledge of metal properties and shop mathematics. Refill, change, and monitor the level of fluids, such as oil and coolant, in machines. Install holding fixtures, cams, gears, and stops to control stock and tool movement, using hand tools, power tools, and measuring instruments. Compute dimensions, unspecified dimensions and machine settings, tolerances, and angles of workpieces or machines, according to specifications and knowledge of metal properties and shop mathematics. Lift metal stock or work pieces manually or using hoists, and position and secure them in machines, using fasteners and hand tools. Move cutters, tool holders or material manually or by turning hand wheels, or engage automatic feeding mechanisms to mill and feed tools to and along work pieces to specifications. Turn valve handles pull levers to direct or start and regulate the flow of coolant or lubricants onto work areas or to coat disks with spinning compounds. Mount attachments and tools, such as relieving or tracing attachments, pantographs, engravers, or routers to perform operations, such as duplicating contours of templates, drilling, boring, or trimming work pieces. Make templates or cutting tools. Record production output.
