JobTitles : Computer Numerical Control Programmer (CNC Programmer), Process Engineer, Programmer, Programer, Project Engineer, Software Engineer, Welding Engineer, CAD CAM Programmer (Computer-Aided Design Computer-Aided Manufacturing Programmer)

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