Core Responsibilities

Primary Functions

  • Set up, adjust, and operate a variety of gear manufacturing machines, which may include CNC or manual gear hobbers, shapers, grinders, and cutters, to produce high-quality gears.
  • Interpret complex engineering blueprints, technical drawings, and Geometric Dimensioning and Tolerancing (GD&T) specifications to determine machining requirements and setup parameters.
  • Select, align, and securely install holding fixtures, cutting tools, attachments, arbors, and materials onto machines to prepare for production runs.
  • Calculate and set machine controls, including speeds, feeds, and depth of cut, to machine parts to precise specifications, often involving complex shop math.
    LAGU- Load and unload parts and components from machinery, either manually or with the assistance of overhead cranes or other lifting devices, ensuring proper seating and alignment.
  • Conduct first-piece, in-process, and final quality inspections using a wide range of precision measuring instruments such as micrometers, calipers, bore gauges, pitch micrometers, and comparators.
  • Monitor machine operations in real-time to detect malfunctions, tool wear, or out-of-tolerance machining, and make necessary adjustments to machine controls or offsets to correct any issues.
  • Perform timely tool and insert changes as required to maintain dimensional accuracy, surface finish, and overall part quality throughout the production run.
  • Deburr and finish machined gear parts using various hand tools and equipment to remove sharp edges and ensure they meet surface finish requirements.
  • Meticulously complete all required production and quality control documentation, including setup sheets, inspection logs, and production records, ensuring accuracy and traceability.
  • Read and interpret CNC programs (G-code and M-code) to verify correct program selection and understand the machining sequence.
  • Verify the conformance of finished workpieces to specifications, frequently using specialized gear checking equipment (e.g., CMM, lead/involute checkers) to measure critical gear tooth geometry.

Secondary Functions

  • Perform routine and preventative machine maintenance, including cleaning, lubricating machinery, and checking fluid levels, to ensure optimal performance and operational longevity.
  • Troubleshoot common machining problems and operational issues, collaborating with maintenance personnel or engineers to resolve more complex equipment failures.
  • Adhere strictly to all company safety policies, procedures, and lockout/tagout (LOTO) protocols to maintain a safe and hazard-free working environment.
  • Maintain a clean, organized, and efficient work area, often applying 5S principles (Sort, Set in Order, Shine, Standardize, Sustain).
  • Assist in the training and mentorship of new or less-experienced operators on machine setup, operation, and safety procedures.
  • Participate actively in continuous improvement initiatives by providing feedback and suggestions to enhance process efficiency, part quality, and workplace safety.
  • Collaborate with the Quality Assurance department to analyze and correct any non-conforming parts and participate in root cause analysis activities.
  • Manage the local inventory of tooling, inserts, and supplies required for the gear production cell to prevent production downtime.
