CMM Programmer

Role Summary We are seeking an experienced CMM Programmer to support precision inspection and dimensional validation for cold plate manufacturing and related liquid-cooling components. This role is responsible for developing, validating, maintaining, and improving CMM programs used to inspect critical features on machined and plated cold plates. The ideal candidate has strong hands‑on experience programming and operating CMM equipment, interpreting complex engineering drawings, applying GD&T, validating measurement methods, and supporting production ramp activities. This person will work closely with Quality Engineering, Manufacturing Engineering, NPI, Operations, and Inspection teams to ensure cold plates meet dimensional, functional, and customer requirements. This role requires someone who can not only program the CMM, but also understand whether the measurement strategy makes sense for the product, process, and risk. Key Responsibilities CMM Programming & Inspection Method Development Create, modify, validate, and maintain CMM programs for cold plates, machined components, and related liquid‑cooling parts. Develop inspection routines based on engineering drawings, GD&T requirements, control plans, CTQs, and customer specifications. Program inspections for critical features such as flatness, parallelism, perpendicularity, hole position, true position, profile, thickness, port locations, sealing surfaces, datum structures, and critical interface dimensions. Establish proper alignment strategies, datum reference frames, probing paths, measurement points, and inspection sequences. Optimize CMM programs for accuracy, repeatability, cycle time, and production usability. Support CMM inspection for prototype, First Article, NPI, ramp, and sustaining production phases. Ensure CMM programs are controlled, revision‑aligned, and properly documented. Cold Plate Dimensional Validation Support dimensional validation of cold plates used in liquid cooling applications. Inspect features related to fluid flow, sealing, mounting, assembly fit, and thermal performance. Develop inspection strategies for machined surfaces, brazed/joined areas, ports, internal/external interfaces, and plated surfaces. Support measurement of features impacted by machining, deburring, cleaning, nickel plating, silver plating, and final finishing processes. Understand how plating thickness, surface condition, burrs, contamination, and part handling can impact dimensional inspection results. Work with Quality and Engineering teams to define inspection methods for CTQs, datums, and critical tolerances. Support dimensional studies related to process capability, Cp/Cpk, GR&R, and supplier/process readiness. CMM Operation & Troubleshooting Operate CMM equipment to perform dimensional inspections as needed. Troubleshoot CMM program issues, measurement variation, fixture issues, probe qualification problems, and alignment errors. Investigate abnormal or questionable CMM results and determine whether the issue is related to the part, program, fixture, setup, probe, datum strategy, or measurement method. Support manual verification when CMM results indicate failures or when measurement correlation is required. Partner with inspectors to ensure CMM programs are easy to run, clearly documented, and production‑ready. Train inspectors on proper CMM program execution, setup requirements, part loading, fixture use, and basic result interpretation. Manual Inspection Correlation & Measurement Validation Correlate CMM results with manual inspection methods where required. Use or support verification with calipers, micrometers, height gauges, pin gauges, bore gauges, indicators, surface plates, optical comparators, thread gauges, and other precision tools. Support measurement system analysis, including GR&R and repeatability studies. Confirm measurement methods are appropriate for tolerance requirements and product risk. Identify and resolve gaps between CMM results, manual measurements, supplier data, and engineering expectations. Support inspection method improvements to reduce false failures, missed defects, and unnecessary inspection variation. NPI, Ramp & Production Support Support NPI builds, pilot runs, process validation, and production ramp for cold plate manufacturing. Participate in reviews of drawings, CTQs, control plans, PFMEAs, inspection plans, and customer requirements. Provide input on inspection feasibility, gage selection, fixture requirements, and measurement strategy. Support inline inspection development where CMM data is needed to monitor process performance. Analyze dimensional trends and provide feedback to Manufacturing Engineering and Quality Engineering. Support root cause investigations by providing accurate measurement data and technical interpretation. Assist with containment, sorting, reinspection, and MRB activities when dimensional issues are identified. Documentation & Quality System Support Maintain controlled CMM programs, inspection plans, setup instructions, and measurement documentation. Ensure CMM programs are aligned with latest drawing revisions, customer requirements, and internal quality standards. Create clear inspection reports and dimensional summaries for Quality, Engineering, Operations, and customer review. Support First Article Inspection documentation and dimensional layout reports. Maintain traceability of inspection results, program revisions, fixtures, probes, and measurement equipment. Support audit readiness by ensuring inspection methods and records are complete, accurate, and repeatable. Required Qualifications 6-8+ years of experience in CMM programming, dimensional inspection, or precision manufacturing quality. Hands‑on experience creating and validating CMM programs. Strong ability to read and interpret engineering drawings, specifications, and GD&T. Strong understanding of datum structures, true position, profile, flatness, perpendicularity, parallelism, and tolerance stack‑up. Experience inspecting precision‑machined components. Ability to troubleshoot CMM programs, fixture issues, probing issues, alignment errors, and measurement variation. Experience correlating CMM inspection results with manual measurement methods. Strong knowledge of precision inspection tools and measurement principles. Ability to work directly with Quality, Engineering, Operations, and Inspection teams in a production environment. Strong documentation, communication, and problem‑solving skills. #J-18808-Ljbffr Plasticos Castella SA
