Core Responsibilities

Primary Functions

Perform comprehensive first article, in-process, and final inspections on newly manufactured or refurbished tools, dies, jigs, and fixtures to ensure full compliance with specifications.
Utilize a wide array of precision measuring instruments, including digital calipers, micrometers, height gauges, bore gauges, and thread gauges, to verify dimensional accuracy.
Operate and, where applicable, program Coordinate Measuring Machines (CMM) to conduct complex 3D inspections on intricate tooling components.
Interpret and apply complex engineering drawings, blueprints, 3D models, and technical specifications, demonstrating a deep understanding of Geometric Dimensioning and Tolerancing (GD&T).
Create, manage, and maintain meticulous inspection records, non-conformance reports, and quality documentation within the company's Quality Management System (QMS).
Conduct routine calibration, verification, and maintenance of all inspection equipment and gauges to ensure their accuracy and traceability to national standards.
Perform specialized tests such as surface finish analysis and material hardness testing to ensure tooling components meet all engineering and performance requirements.
Collaborate directly with toolmakers, machinists, and design engineers to troubleshoot and resolve dimensional discrepancies or quality issues identified during inspection.
Lead or participate in root cause analysis investigations for non-conforming tools and contribute to the development of robust corrective and preventive actions (CAPA).
Manage the quarantine area and the disposition process for non-conforming materials and tools, ensuring proper documentation and process adherence.
Validate and approve tooling and fixtures received from external suppliers, confirming they meet all company quality standards before they are released to production.
Assist in the development, documentation, and refinement of standard inspection procedures and work instructions to enhance inspection efficiency and repeatability.
Maintain a clean, organized, and safe work environment within the quality inspection lab, strictly adhering to all 5S and safety protocols.
Act as a subject matter expert on metrology and inspection best practices, providing technical support and guidance to other team members and departments.
Conduct and analyze gage repeatability and reproducibility (Gage R&R) studies to validate the capability and reliability of measurement systems.
Document and track the complete lifecycle of production tools, including usage, wear patterns, repairs, and calibration schedules, to predict maintenance needs.
Initiate and manage Material Review Board (MRB) activities for any tools or components that fall outside of specified tolerances.
Utilize Statistical Process Control (SPC) methods to monitor tool manufacturing processes, identify negative trends, and drive process improvements.
Verify and file certifications for outside processes such as heat treatment, plating, and coating to ensure they align with engineering requirements.
Prepare and submit detailed First Article Inspection Reports (FAIRs), often in accordance with standards like AS9102, for customer or internal approval.
Perform thorough visual inspections to identify cosmetic defects, surface imperfections, burrs, or incorrect assembly of tooling.

Secondary Functions

Support continuous improvement initiatives by providing data and feedback on tooling performance and quality trends.
Assist in training apprentices and junior team members on proper inspection techniques and the safe use of metrology equipment.
Collaborate with the engineering and purchasing departments to review new supplier capabilities and qualifications.
Participate in safety committee meetings and contribute to promoting the overall safety culture of the facility.
