Tasks: |
Write programs in the language of a machine's controller and store programs on media such as punch tapes, magnetic tapes, or disks. 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. Write instruction sheets and cutter lists for a machine's controller to guide setup and encode numerical control tapes. Observe machines on trial runs or conduct computer simulations to ensure that programs and machinery will function properly and produce items that meet specifications. Enter computer commands to store or retrieve parts patterns, graphic displays, or programs that transfer data to other media. Modify existing programs to enhance efficiency. Determine reference points, machine cutting paths, or hole locations, and compute angular and linear dimensions, radii, and curvatures. 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. Perform preventative maintenance or minor repairs on machines.
