  • Interpret and apply complex information from engineering drawings, blueprints, and digital product definitions, with a heavy focus on Geometric Dimensioning and Tolerancing (GD&T).
  • Analyze and interpret analytical gear chart data, including lead, profile, index, pitch, and runout, to identify non-conformances and manufacturing process deviations.
  • Generate detailed and accurate first article, in-process, and final inspection reports, meticulously documenting all findings, measurements, and pass/fail criteria.
  • Conduct regular calibration, verification, and maintenance of all gear lab inspection equipment and gauges to ensure their accuracy, repeatability, and reliability.
  • Collaborate directly with manufacturing engineers and machinists to troubleshoot production issues, providing precise data and feedback to guide corrective actions and process improvements.
  • Execute First Article Inspection (FAI) in accordance with AS9102 standards, compiling comprehensive documentation packages for customer submission and approval.
  • Develop, write, and validate new inspection programs on gear analyzers and CMMs for new product introductions and engineering changes.
  • Utilize a wide range of standard metrology hand tools, including micrometers, calipers, bore gages, indicators, and height gages, for manual checks and verifications.
  • Apply knowledge of AGMA, ISO, and other relevant industry standards to determine the acceptability of gear quality and classify gears accordingly.
  • Perform root cause analysis on non-conforming parts and actively participate in the Corrective and Preventive Action (CAPA) process to prevent recurrence.
  • Maintain a clean, organized, and environmentally controlled gear laboratory, adhering to 5S principles and all safety protocols.
  • Manage the non-conforming material process, including part segregation, identification, and disposition in coordination with the Material Review Board (MRB).
  • Conduct surface finish, roundness, and form testing on gear teeth and related features using equipment like a profilometer or Talyrond.
  • Review and validate incoming supplier data and perform receiving inspections on critical externally sourced components to ensure they meet specifications.
  • Maintain meticulous and organized digital and hard-copy records of all inspection activities, results, and equipment calibration history within the Quality Management System (QMS).
  • Provide technical support and mentorship to junior inspectors and manufacturing personnel on gear characteristics and proper measurement techniques.
  • Participate actively in internal and external quality audits (e.g., AS9100, customer audits), presenting inspection records and demonstrating process compliance.
  • Operate Coordinate Measuring Machines (CMMs) using specialized software packages like Quindos, PC-DMIS Gear, or Calypso for non-standard gear geometries and features.
  • Assist in evaluating and selecting new metrology equipment and technologies to enhance the lab's capabilities and efficiency.

Secondary Functions

  • Support engineering and manufacturing teams with ad-hoc inspection data and exploratory analysis of gear performance.
  • Contribute to the continuous improvement of the quality department's inspection strategy and metrology roadmap.
  • Collaborate with design and manufacturing engineering to translate new product gear requirements into robust inspection plans.
  • Participate in daily production meetings and quality reviews, representing the gear lab and providing critical feedback.
