Core Responsibilities

Primary Functions

Perform complex dimensional and visual inspections of machined parts, components, and assemblies at various production stages, including first article (FAI), in-process, receiving, and final inspection.
Set up, program, and operate Coordinate Measuring Machines (CMM), utilizing software such as PC-DMIS, Zeiss Calypso, or Mitutoyo MCOSMOS, to execute automated inspection routines on high-tolerance components.
Interpret complex engineering drawings, blueprints, technical specifications, and 3D CAD models to determine inspection requirements, critical dimensions, and tolerance callouts based on GD&T standards (ASME Y14.5).
Utilize a wide array of precision hand-held measuring instruments, including micrometers, calipers, height gauges, bore gauges, indicators, and thread gauges, to verify component dimensions.
Operate and interpret results from advanced optical and non-contact inspection equipment, such as vision systems, optical comparators, profilometers, and surface roughness testers.
Generate and meticulously document detailed inspection reports, including First Article Inspection Reports (FAIR) in accordance with AS9102 standards.
Identify, document, and quarantine non-conforming products using the company's quality management system, and create detailed Non-Conforming Material Reports (NCMRs).
Verify material and special processing certifications against purchase order and drawing requirements to ensure full traceability and compliance.
Calibrate and maintain inspection equipment to ensure its accuracy and reliability, managing calibration schedules and records.
Approve finished products by confirming they meet all specifications and release conforming lots for shipment.
Conduct thorough root cause analysis for identified discrepancies and collaborate with engineering and production teams to implement effective corrective and preventive actions (CAPA).
Validate the effectiveness of corrective actions through follow-up inspections and monitoring to prevent the recurrence of defects.
Perform surface plate layouts and complex manual inspections for parts that cannot be measured using automated systems.
Review and approve supplier-provided inspection data, performing source inspections at supplier facilities as required.
Witness and verify product testing procedures to ensure they are conducted according to defined protocols and that results are accurately recorded.

Secondary Functions

Provide technical guidance and mentorship to junior inspectors and manufacturing personnel on proper measurement techniques and interpretation of quality standards.
Participate in internal and external audits of the Quality Management System (QMS) to ensure ongoing compliance with standards like ISO 9001 and AS9100.
Collaborate with Manufacturing and Engineering departments during design reviews and process development to provide input on manufacturability and inspectability (DFM/DFI).
Assist in developing and refining inspection methods, work instructions, and quality control procedures to enhance efficiency and accuracy.
Maintain organized and accurate records of inspection results, test data, and quality documentation in the company's database or ERP system.
