Computer Numerically Controlled Tool Operators

• Calculate machine speed and feed ratios and the size and position of cuts.
• Implement changes to machine programs, and enter new specifications, using computers.
• Check to ensure that workpieces are properly lubricated and cooled during machine operation.
• Input initial part dimensions into machine control panels.
• Transfer commands from servers to computer numerical control (CNC) modules, using computer network links.
• Insert control instructions into machine control units to start operation.
• Monitor machine operation and control panel displays, and compare readings to specifications to detect malfunctions.
• 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.

• Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences.
• Set up future jobs while machines are operating.
• Write simple programs for computer-controlled machine tools.
• Modify cutting programs to account for problems encountered during operation, and save modified programs.
• Set up and operate computer-controlled machines or robots to perform one or more machine functions on metal or plastic workpieces.
• 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.
• Maintain machines and remove and replace broken or worn machine tools, using hand tools.
• 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.
• Measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures.
• Remove and replace dull cutting tools.
