TITLE(s): TOOL PROGRAMMER, NUMERICAL CONTROL (any industry) alternate titles: computer-programmer,
numerical control; programmer, numerical control; tool programmer
Plans numerical control program to control contour-path machining of metal parts on automatic
machine tools: Analyzes drawings, sketches, and design data of part to determine dimension and
configuration of cuts, selection of cutting tools, and machine speeds and feed rates, according to
knowledge of machine shop processes, part specifications, and machine capabilities. Determines
reference points and direction of machine cutting paths. Computes angular and linear dimensions,
radii, and curvatures, and outlines sequence of operations required to machine part. Prepares
geometric layout on graph paper or using computer-assisted drafting software to show location of
reference points and direction of cutting paths, using drafting instruments or computer. Writes
instruction sheets and cutter lists to guide setup and operation of machine. Writes program of
machine instructions in symbolic language to encode numerical control tape or direct numerical
control data base to regulate movement of machine along cutting path. Compares encoded tape or
computer printout with original program sheet to assure accuracy of machine instructions. Revises
program to eliminate instruction errors or omissions. Observes operation of machine on trial run to
prove taped or programmed instructions.
