- Align and secure holding fixtures, cutting tools, attachments, accessories, and materials onto machines.
- Select the appropriate tools, machines, and materials to be used in preparation of machinery work.
- Monitor the feed and speed of machines during the machining process.
- Machine parts to specifications using machine tools such as lathes, milling machines, shapers, or grinders.
- Set up, adjust, and operate all of the basic machine tools and many specialized or advanced variation tools to perform precision machining operations.
- Measure, examine, and test completed units to detect defects and ensure conformance to specifications, using precision instruments such as micrometers.
- Set controls to regulate machining, or enter commands to retrieve, input, or edit computerized machine control media.
- Position and fasten work pieces.
- Maintain industrial machines, applying knowledge of mechanics, shop mathematics, metal properties, layout, and machining procedures.
- Observe and listen to operating machines or equipment to diagnose machine malfunctions and to determine need for adjustments or repairs.
- Check work pieces to ensure that they are properly lubricated and cooled.
- Lay out, measure, and mark metal stock to display placement of cuts.
- Study sample parts, blueprints, drawings, and engineering information to determine methods and sequences of operations needed to fabricate products, and determine product dimensions and tolerances.
- Confer with engineering, supervisory, and manufacturing personnel to exchange technical information.
- Program computers and electronic instruments such as numerically controlled machine tools.
- Operate equipment to verify operational efficiency.
- Clean and lubricate machines, tools, and equipment to remove grease, rust, stains, and foreign matter.
- Design fixtures, tooling, and experimental parts to meet special engineering needs.
- Evaluate experimental procedures, and recommend changes or modifications for improved efficiency and adaptability to setup and production.
