Description:
The CNC Machinist Apprentice sets up and operates a variety of machine tools to produce precision metal parts and instruments to specification. This is a paid, entry-level training position within Bay Cast Technologies' U.S. Department of Labor Registered Apprenticeship Program. The apprentice works under the direct supervision of a journeyworker machinist and progresses through a structured combination of on-the-job learning (6,004–7,500 hours) and related technical classroom instruction (a minimum of 885 hours), applying knowledge of mechanics, mathematics, metal properties, layout, and machining procedures. Upon successful completion of the program, the apprentice is eligible for a U.S. Department of Labor Certificate of Completion as a journey-level Machinist.
Essential Duties and Responsibilities
Under supervision, and with responsibilities expanding as competencies are achieved, the apprentice will:
- Measure, calculate, and verify part dimensions and tolerances using micrometers, vernier calipers, and other precision instruments.
- Set up and operate cutting equipment, including lathes, milling machines, shapers, and grinders, to machine parts to specification.
- Set up and operate grinding equipment and metal or plastic forming equipment.
- Program computers and electronic instruments, including numerically controlled (CNC) machine tools, to perform production tasks.
- Monitor the feed, speed, and output of machines during the machining process to ensure proper functioning and conformance to specification.
- Study and interpret blueprints, drawings, and engineering information to determine operational methods and sequences.
- Maintain machine tools and production equipment in proper operating condition.
- Fit, assemble, and repair machine tools, parts, and fixtures.
- Support metalworking projects from planning and fabrication through assembly, inspection, and testing.
- Align and secure holding fixtures, cutting tools, attachments, and accessories onto machines; install repaired or new parts and equipment.
- Conduct test runs of production equipment and experimental models to verify operational efficiency and design feasibility.
- Confer with numerical control programmers, engineering, supervisory, and manufacturing personnel to exchange technical information and ensure programs and output meet specification.
- Evaluate machining procedures and recommend changes or modifications to improve efficiency, quality, or adaptability.
- Design or assist in designing tooling, fixtures, or experimental parts to meet special engineering needs.
- Diagnose machine tool malfunctions and determine the need for adjustments or repairs; dismantle equipment as needed to examine and replace defective parts.
- Lay out, measure, and mark metal stock to indicate placement of cuts.
- Set up and operate metalworking, brazing, heat-treating, welding, or cutting equipment as required.
- Sort and dispose of scrap or waste material in accordance with company policy and environmental regulations.
- Attend and satisfactorily complete all required related instruction coursework outside of scheduled work hours (unpaid, per program requirements).
- Follow all safety protocols and wear required personal protective equipment (PPE) at all times.
- Perform other related duties as assigned by the supervising journeyworker or shop supervisor.
