Reports to: Quality Manager

JM Fabrication is seeking a CMM Operator / Quality Inspector with PC-DMIS experience to perform dimensional inspections of manufactured parts and assemblies. This role uses a Coordinate Measuring Machine (CMM) and precision measuring instruments to verify compliance with engineering drawings, Geometric Dimensioning and Tolerancing (GD&T) requirements, and customer specifications.

The ideal candidate has hands‑on CMM experience, strong blueprint‑reading skills, and the judgment to recognize questionable measurement results and communicate quality concerns. Experience programming in PC‑DMIS is preferred.

• Set up and operate CMM equipment using PC‑DMIS to run approved inspection programs, review measurement results, and generate inspection reports.
• Verify part identification, drawing revision, inspection program, fixturing, probe qualification, and part alignment before accepting inspection results.
• Perform first article inspection (FAI), in‑process inspection, final inspection, and receiving inspection as assigned.
• Read and interpret engineering blueprints, technical specifications, and GD&T per ASME Y14.5, using the revision required by the drawing or customer.
• Apply GD&T requirements to inspection setups and results, including datum reference frames, feature control frames, basic dimensions, position, profile, flatness, perpendicularity, parallelism, and runout.
• Interpret material condition requirements, including maximum material condition (MMC), least material condition (LMC), regardless of feature size (RFS), and bonus tolerance, where applicable.
• Use micrometers, calipers, height gauges, dial indicators, gauge pins, and surface plates to perform manual inspections and verify measurements.
• Investigate unexpected readings and elevate concerns involving part setup, alignment, inspection programs, or drawing interpretation.
• Document inspection results accurately and maintain traceability to the applicable part, job, drawing revision, and inspection equipment.
• Identify, document, and segregate nonconforming material according to company procedures. Communicate discrepancies promptly to Quality and Production.
• Support AS9102 first‑article inspection reports when required by the customer.
• Verify equipment calibration status, perform routine operator checks and cleaning, and report equipment damage or performance concerns.
• Support root‑cause investigations, corrective actions, and improvements to inspection methods.
• Maintain an organized inspection area and follow company quality and safety procedures.

• Two or more years of dimensional inspection experience in manufacturing, including hands‑on CMM operation.
• Practical experience using PC‑DMIS to load and run existing CMM programs, verify alignments, and interpret inspection results.
• Ability to read engineering drawings and apply GD&T to actual part setups and measurements.
• Proficiency with precision measuring instruments and manual dimensional inspection.
• Understanding of how fixturing, alignment, cleanliness, and temperature can affect measurement accuracy.
• Strong attention to detail and the ability to maintain accurate, complete inspection records.
• Clear communication skills and the ability to explain inspection findings to Quality and Production personnel.
• Basic computer skills, including Microsoft Excel and electronic inspection or manufacturing records.
• Ability to work independently within established…
