Key Tasks

• 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.
• Compare encoded tapes or computer printouts with original part specifications and blueprints to verify accuracy of instructions.
• Prepare geometric layouts from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.
• Perform preventative maintenance or minor repairs on machines.
• Order tooling for jobs.
• 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.
