Computer Numerical Control Programmer

Provides programming support for machining parts, tools, or sheet metal on numerically controlled machine tools. Ensures parts conform to dimensional specifications and equipment achieves throughput efficiency.

Essential Functions

• Provides programming support for machining parts, tools, or sheet metal on numerically controlled machine tools by writing programs of machine instructions in symbolic language to encode numerical control tape or direct numerical control database to regulate movement of machine along cutting path.
• Selects proper cutting tools for each part, by taking into consideration such factors as speeds, types of cutters, feeds, and control system limitations to safely and economically produce a part to the manufacturing engineering specification or drawing.
• Selects program routines for the most efficient computer calculation of dimensional and machining requirements for each part by computing angular and linear dimensions, radii, and curvatures, and outlining sequence of operations required to machine the part.
• Determine dimension and configuration of cuts, selection of cutting tools, machine speeds, and feed rates by analyzing drawings, sketches, and design data of part.
• Shows location of reference points and direction of cutting paths by preparing geometric layouts on graph paper or by using computer-assisted drafting / manufacturing software.
• Modifies existing parts programs for engineering changes or program improvements and revises programs to eliminate instruction errors or omissions.
• Observes operation of machine on trial run to prove taped or programmed instructions. Compares encoded tape or computer printout with original program sheet to assure accuracy of machine instructions.
• Analyzes proposed changes in methods and materials and contributes to continuous improvement and key lean manufacturing / production activities. Recommends cost reduction opportunities and may be assigned to special projects.
• Maintains technical knowledge by attending educational workshops and reviewing technical publications.
• Supports the team by accomplishing related results as needed. Work assignments may include cross-functional or project team responsibilities.
