The purpose of this position is to support the department’s ability to achieve its goals and objectives. This includes the following: Designs and writes numerical control programs and processes that allow PAC to exceed customer expectations for quality and on-time delivery. These programs control contour-path machining of metal and non-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 using CAD-CAM drafting software to show location of reference points and direction of cutting paths. Writes instruction sheets and cutter lists to guide setup and operation of the machine. Writes programs of machine instructions in symbolic language to encode numerical control and sends these instructions to a database to regulate movement of machine along cutting paths. Compares computer command results with original program intent to assure accuracy of machine instructions. Revises programs to eliminate instruction errors or omissions. Observes operation of machine on trial run to prove programmed instructions.
