CNC Setup & Operate

Responsibilities Measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures. Mount, install, align, and secure tools, attachments, fixtures, and workpieces on machines, using hand tools and precision measuring instruments. Stop machines to remove finished workpieces or to change tooling, setup, or workpiece placement, according to required machining sequences. Transfer commands from servers to computer numerical control (CNC) modules, using computer network links. Check to ensure that workpieces are properly lubricated and cooled during machine operation. Set up and operate computer-controlled machines or robots to perform one or more machine functions on metal or plastic workpieces. Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences. Listen to machines during operation to detect sounds such as those made by dull cutting tools or excessive vibration, and adjust machines to compensate for problems. Remove and replace dull cutting tools and monitor machine operation and control panel displays, comparing readings to specifications to detect malfunctions. Enter commands or load control media into machine controllers to retrieve programmed instructions. Modify cutting programs to account for problems encountered during operation, and save modified programs. Calculate machine speed and feed ratios and the size and position of cuts. Adjust machine feed and speed, change cutting tools, or adjust machine controls when automatic programming is faulty or if machines malfunction. Lift workpieces to machines manually or with hoists or cranes. Stack or load finished items, or place items on conveyor systems. Control coolant systems. Maintain machines and remove and replace broken or worn machine tools, using hand tools. Confer with supervisors or programmers to resolve machine malfunctions or production errors or to obtain approval to continue production. Set up future jobs while machines are operating. Clean machines, tooling, or parts, using solvents or solutions and rags. Adjust machine controls and change tool settings to keep dimensions within specified tolerances. Replace worn tools, and sharpen dull cutting tools and dies, using bench grinders or cutter-grinding machines. Inspect sample workpieces to verify conformance with specifications, using instruments such as gauges, micrometers, and dial indicators. Start lathe or turning machines and observe operations to ensure that specifications are met. Position, secure, and align cutting tools in toolholders on machines, using hand tools, and verify their positions with measuring instruments. Study blueprints, layouts or charts, and job orders for information on specifications and tooling instructions, and to determine material requirements and operational sequences. Select cutting tools and tooling instructions according to written specifications or knowledge of metal properties and shop mathematics. Move controls to set cutting speeds and depths and feed rates, and to position tools in relation to workpieces. 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 unspecified dimensions and machine settings, using knowledge of metal properties and shop mathematics. Lift metal stock or workpieces manually or using hoists, and position and secure them in machines, using fasteners and hand tools. Turn valve handles to direct the flow of coolant onto work areas or to coat disks with spinning compounds. Qualifications 2+ years of CNC Setup and Operate experience (preferred).
