Summary

: Sets up and operates computer numerical control (CNC) lathe machining centers to perform machine functions such as boring, facing, and threading parts of metallic workpieces such as castings, forgings and bar stock by performing the following duties. Essential Functions:

Plans machining by studying work orders, blueprints, engineering plans, materials, specifications, orthographic drawings, reference planes, locations of surfaces, and machining parameters; interpreting geometric dimensions and tolerances (GD&T).

Programs CNC machines by entering instructions, including zero and reference points; setting tool registers, offsets, compensation, and conditional switches; calculating requirements, including basic math, geometry, and trigonometry; proving part programs.

Sets-up CNC machines by installing and adjusting three- and four-jaw chucks, tools, attachments, collets, bushings, cams, gears, stops, and stock pushers; indicating...
