Computer Numerically Controlled Machine Tool Programmers, Metal and Plastic

Tasks


Core Tasks Include:

  • Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes.
  • Revise programs and/or tapes to eliminate errors, and retest programs to check that problems have been solved.
  • Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data in order to calculate dimensions, tool selection, machine speeds, and feed rates.
  • Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures.
  • Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications.
  • Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions.
  • Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers.
  • Write programs in the language of a machine's controller and store programs on media such as punch tapes, magnetic tapes, or disks.
  • Modify existing programs to enhance efficiency.
  • Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media.
  • Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.

Supplemental Tasks Include:

  • Write instruction sheets and cutter lists for a machine's controller in order to guide setup and encode numerical control tapes.
  • Sort shop orders into groups to maximize materials utilization and minimize machine setup time.
  • Draw machine tool paths on pattern film, using colored markers and following guidelines for tool speed and efficiency.
  • Align and secure pattern film on reference tables of optical programmers, and observe enlarger scope views of printed circuit boards.
