Coordinate Measuring Inspector

The inspector writes automated inspection routines in metrology software such as PC DMIS or ZEISS Calypso, translating 2D engineering blueprints and 3D CAD models into automated touch trigger or continuous scanning probe inspection routines. Conforming to ASME Y14.5 Geometric Dimensioning and Tolerancing GD and T and ISO 10360 standards, the inspector establishes reference datums, measures feature sizes, true positions, profile of a surface tolerances, concentricity, perpendicularity, and runout. The specialist selects and calibrates delicate ruby and silicon nitride styli on articulating probe heads, verifying probe tip sphericity against certified ceramic calibration spheres.

While automated metrology software executes probe paths and generates graphical inspection color maps, the physical physics of dimensional measurement introduces subtle environmental errors that software alone cannot resolve. Part temperature expansion differences between aluminum components and granite machine tables, elastic deflection caused by stylus probe contact force, dust particles skewing micro inch surface readings, and improper part clamping that induces mechanical distortion demand rigorous manual fixture setup, temperature normalization, and physical calibration by certified human metrology inspectors.

At 07:00, the inspector enters the climate controlled quality metrology laboratory, where the ambient temperature is tightly regulated at 20 degrees Celsius within 0.5 degrees. An aluminum aerospace wing rib machined during the night shift has been sitting on the granite normalization table for six hours to equalize temperature. The inspector verifies the calibration of the ZEISS PRISMO CMM, commanding the scanning probe to touch a certified ceramic master sphere at twenty different vector angles. The machine reports a probe tip qualification standard deviation of 0.0003 millimeters, confirming micro inch accuracy. Carefully mounting the wing rib onto three nylon standoffs

using modular aluminum fixture arms, the inspector applies light clamping force to avoid mechanical bending. Opening ZEISS Calypso, the inspector recalls the programmed inspection routine. The scanning probe glides across the granite table, touching sixty eight fastener holes, twenty two datum surfaces, and scanning the continuous 3D contour of the outer airfoil skin. The software compiles the inspection report, generating an AS9102 first article inspection sheet. The inspector reviews the true position callouts, observing that hole thirty four shows a true position deviation of 0.038 millimeters against a maximum allowable.

A Coordinate Measuring Machine CMM Metrology Inspector programs, calibrates, operates, and maintains high precision bridge, gantry, and optical coordinate measuring systems inside climate controlled quality control laboratories. Serving as the ultimate authority on dimensional accuracy across aerospace machining, automotive powertrain fabrication, medical orthopedic device manufacturing, and precision toolmaking industries, the inspector measures complex mechanical geometries down to sub micron tolerances.

Core responsibilities include program and operate automated coordinate measuring machines cmm using pc dmis or zeiss calypso., operational coordination, and ensuring strict adherence to Kenyan statutory frameworks and quality standards.

Key organizations hiring for this role include Kenya Nuclear Regulatory Authority KNRA, Kenyatta University Teaching Research and Referral Hospital KUTRRH, Kenyatta National Hospital KNH Cancer Centre, Aga Khan University Hospital Nairobi Oncology Division, alongside expanding opportunities in Nairobi, Mombasa, Kisumu, and regional infrastructure projects.
