MACHINIST (TITLE 32)

Military Grades: E-1 through E-7 GENERAL EXPERIENCE: Must have experience or training that has provided the candidate with a basic knowledge of machining processes. Must have the ability to use drill presses, shapers, planers, and other types of associated machine tools.

SPECIALIZED EXPERIENCE: Must have 18 months experience or training performing the full range of machining operations on most types of conventional or CNC machine tools and their various attachments; experience or training in planning and lay out work from blueprints, worksheets and other drawings that may have missing or incorrect information; skill in applying shop mathematics in establishing needed dimensions, such as those required for chasing threads or machining angular surfaces; locating and marking surfaces and angles to be machined; skill in programming machining operations, setting up and operating CNC machine tools; knowledge of and ability to apply advanced shop mathematics such as geometric and trigonometric formulas to make computation for laying out work, machining pieces at unusual or compound angles, determining gear ratios pitch, angles and other similar exact or precision dimension.

As a Machinist, WG-3414-11, you will fabricate complex and non-routine items that require numerous intricate steps, precise measurements, unusual and compound angles, or nonstandard applications of standard equipment. Plan and lay out work from blueprints, sketches, drawings, or specifications.

Perform machine setups using advanced shop mathematics, and geometric and trigonometric formulas, to compute compound angles, angular indexing, hole patterns, pitch lead, and pitch diameters for various standard and non-standard threads.

Set up and operate most types of conventional and/or Computer Numerical Control (CNC) machine tools such as lathes; vertical and horizontal boring mills; bench, plane, or universal milling machines; shapers and planers; internal and external grinders, thread grinders; and radial drills. Perform precision handwork to finish, fit, and assemble machined parts.
