A Coordinate Measuring Machine (CMM) Specialist specializes in the use of CMMs that measure an object's physical geometrical characteristics as part of the manufacturing process.
Perform dimensional inspections of mechanical parts using CMM, laser trackers, portable arms, optical scanners, and other calibrated instruments.
Jigs & Tooling:
Inspect and validate jigs, fixtures, and assembly tools to ensure design specifications and functional dimensions are met. Support maintenance for periodic re-calibration and re-qualification.
Assembly Verification:
Execute in-jig measurements to confirm proper positioning and alignment. Identify deviations such as gap, flush, and hole pattern errors to support First Article Inspections (FAI).
Conformity:
Verify parts against 2D drawings, 3D CAD models, and strict GD&T specifications.
Deviation Analysis:
Classify anomalies (systematic vs. random) and identify root causes using historical data and trending.
Engineering Support:
Interpret GD&T and propose improvements to tolerance schemes. Provide measurement strategies for new production lines and participate in PFMEA discussions.
Corrective Action:
Propose and implement solutions in collaboration with Engineering, Tooling, and Production teams. Generate detailed measurement reports (PDF + raw data) including pass/fail status and traceability. Issue Non-Conformance Reports (NCR) with documented evidence. Maintain metrology dashboards and equipment calibration certificates. The Expert will operate or supervise the use of:
Hardware:
CMM (bridge or horizontal), Laser Trackers, Photogrammetry, and Portable Arms (Faro, Hexagon, etc.).
Hand Tools:
Surface plates, micrometers, calipers, and gauges.
Software:
Proficiency in PolyWorks, PC-DMIS, Metrolog X4, or equivalent industry-standard platforms.
Maintenance:
Ensure the proper calibration, traceability, and safe handling of all measurement instruments.
