Machinists set up fixtures, cutting tools, and CNC programs, adjusting offsets as needed to maintain dimensional accuracy. They perform deburring operations, basic and advanced preventative maintenance, and troubleshoot machining processes to optimize performance.

Experienced machinists are proficient in using inspection tools such as height gauges, air gauges, and bench inspection equipment. At the highest level, they are capable of setting up and running all site-specific CNC and conventional machines, designing and manufacturing complex tooling, and mentoring junior machinists while contributing to continuous improvement initiatives.

• Perform basic CNC program operations; understanding and editing G Code (e.g., feed/speed adjustments, adding passes) may be required depending on experience.
• Design and set up complex tooling and part layouts (depending on experience).
• Train and mentor other machinists (depending on experience).
• Follow all safety policies (PPE, machine operation, LOTO), quality standards, and 6S organizational practices.
• Perform other duties as assigned.
