What this job is
Develop programs to control machining or processing of materials by automatic machine tools, equipment, or systems. May also set up, operate, or maintain equipment.
What they do day to day
- Determine the sequence of machine operations, and select the proper cutting tools needed to machine workpieces into the desired shapes.
- Analyze job orders, drawings, blueprints, specifications, printed circuit board pattern films, and design data to calculate dimensions, tool selection, machine speeds, and feed rates.
- Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications.
- Write programs in the language of a machine's controller and store programs on media, such as punch tapes, magnetic tapes, or disks.
- 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.
- Revise programs or tapes to eliminate errors, and retest programs to check that problems have been solved.
- Modify existing programs to enhance efficiency.
- Enter coordinates of hole locations into program memories by depressing pedals or buttons of programmers.
- Sort shop orders into groups to maximize materials utilization and minimize machine setup time.
