Computer-Controlled Machine Tool Operators, Metal and Plastic

• 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.
• Insert control instructions into machine control units to start operation.
• Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences.
• Enter commands or load control media, such as tapes, cards, or disks, into machine controllers to retrieve programmed instructions.
• Monitor machine operation and control panel displays and compare readings to specifications to detect malfunctions.
• Remove and replace dull cutting tools.
• 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.
• 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.
• Implement changes to machine programs and enter new specifications, using computers.
• Set up future jobs while machines are operating.
• Clean machines, tooling, or parts, using solvents or solutions and rags.
