Tasks for Numerical Tool and Process Control Programmers
- Prepares geometric layout from graphic displays, using computer-assisted drafting software or drafting instruments and graph paper.
- Sorts shop orders into groups to maximize materials utilization and minimize machine setup.
- Reviews shop orders to determine job specifications and requirements.
- Loads and unloads disks or tapes and observes operation of machine on trial run to test taped or programmed instructions.
- Depresses pedal or button of programmer to enter coordinates of each hole location into program memory.
- Moves reference table to align pattern film over circuit board holes with reference marks on enlarger scope.
- Aligns and secures pattern film on reference table of optical programmer and observes enlarger scope view of printed circuit board.
- Determines reference points, machine cutting paths, or hole locations and computes angular and linear dimensions, radii, and curvatures.
- Compares encoded tape or computer printout with original program sheet to verify accuracy of instructions.
- Draws machine tool paths on pattern film, using colored markers and following guidelines for tool speed and efficiency.
- Enters computer commands to store or retrieve parts patterns, graphic displays, or programs to transfer data to other media.
- Revises numerical control machine tape programs to eliminate instruction errors and omissions.
- Analyzes drawings, specifications, printed circuit board pattern film, and design data to calculate dimensions, tool selection, machine speeds, and feed rates.
- Writes instruction sheets, cutter lists, and machine instructions programs to guide setup and encode numerical control tape.
