Machinist Class B; MM

Scope of Work

As a Machinist, you will program, set‑up, adjust, and operate manual and/or Computer Numerical Control (CNC) machining centers, lathes, and milling machines where detailed operating procedures are prescribed. Manual machining involves special one‑off or prototype parts.

• Perform tasks with moderate supervision.
• Study blueprints, sketches, drawings and specifications.
• Sample parts to determine critical dimensions, tolerances of finished work pieces, sequence of operations, and set‑up requirements.
• Create CNC programs from engineering drawings.
• Determine the best possible procedure, set up machines, and proficiently operate manual and CNC machining and turning centers to achieve required specifications.
• Set up and operate multiple CNC machining and turning centers producing high quality parts.
• Recall programs, determine edits and offsets, and make modifications as required.
• Monitor parts production constantly to ensure adherence to blueprint tolerances.
• Select, align, and secure holding fixtures, cutting tools, attachments, accessories, and materials on machines.
• Change and adjust tooling as required.
• Shape, sharpen, set cutters, and adjust own tools to achieve desired tolerances.
• Set up bore gauges and other inspection equipment.
• Inspect own work at each step to enable timely continuation and ensure quality parts.
• Demonstrate excellent productivity on a large variety of complicated parts and offer creative/innovative machining, tooling and fixturing improvement solutions to supervision to reduce production costs and improve quality.
• Complete all required paperwork including labor reporting and documentation of quality control and material movement.
• Work safely and maintain the work area with high standards of housekeeping.
• Perform required preventative maintenance activities on machinery and/or equipment operated.
• Perform work in lower classifications when assigned, i.e., drills, saws, press brake, etc., and assist in higher classifications.
• Perform other duties as assigned by supervision.

• Minimum of 1 year experience.
• GED or High School Diploma.

• CNC programming experience.
• Knowledge and experience of machining practices and techniques.
• Basic mechanical principles.
• Shop mathematics.
• Blueprint reading.
• Measuring procedures – using precision measuring tools.
• Standing for long periods, bending, reaching, sitting; medium to heavy lifting 25‑100 pounds several times per day; visual acuity and hand dexterity.
• Knowledge of Rottler Acu‑Rite CNC controls.
• Forklift operation experience.
• Knowledge of boring machines.

• Typical hours:
  Monday through Friday, 8:00 a.m. – 4:00 p.m.
• Weekend hours as necessary.
