Will “CNC Machine Operator (Computer Numerical Control Machine Operator)” be Automated?

Core Skills & Abilities

• Write programs in the language of a machine's controller and store programs on media, such as punch tapes, magnetic tapes, or disks.

• Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data to calculate dimensions, tool selection, machine speeds, and feed rates.

• Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.

• Modify existing programs to enhance efficiency.

• Perform preventative maintenance or minor repairs on machines.

• Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers.

• Write instruction sheets and cutter lists for a machine's controller to guide setup and encode numerical control tapes.

• Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards.

• Order tooling for jobs.

• Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes.

• Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media.

• 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.

• Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications.

• 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.
