51-9161 Computer Numerically Controlled Tool Operators
Operate computer-controlled tools, machines, or robots to machine or process parts, tools, or other work pieces made of metal, plastic, wood, stone, or other materials. May also set up and maintain equipment.
MN DEED Link
Occupation Tasks
- 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.
- Maintain machines and remove and replace broken or worn machine tools, using hand tools.
- Control coolant systems.
- Clean machines, tooling, or parts, using solvents or solutions and rags.
- Lift workpieces to machines manually or with hoists or cranes.
- 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.
- Check to ensure that workpieces are properly lubricated and cooled during machine operation.
- Transfer commands from servers to computer numerical control (CNC) modules, using computer network links.
- Confer with supervisors or programmers to resolve machine malfunctions or production errors or to obtain approval to continue production.

Occupation Tasks
- Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards.
- Draw machine tool paths on pattern film according to guidelines for tool speed and efficiency, using colored markers.
- Sort shop orders into groups to maximize materials utilization and minimize machine setup time.
- Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures.
- Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media.
- Draw machine tool paths on pattern film according to guidelines for tool speed and efficiency, using colored markers.
- Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions.
- Revise programs or tapes to eliminate errors, and retest programs to check that problems have been solved.
- Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.
- Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data to calculate dimensions, tool selection, machine speeds, and feed rates.
