Core Responsibilities

Primary Functions

Perform comprehensive first article inspections (FAI), in-process checks, and final inspections on new, repaired, and modified tooling, dies, molds, jigs, and fixtures to ensure strict adherence to design specifications.
Utilize a wide array of advanced precision measuring instruments, including Coordinate Measuring Machines (CMM), vision systems, optical comparators, surface profilometers, micrometers, calipers, and height gauges.
Interpret complex engineering drawings, blueprints, 3D CAD models, and technical specifications, applying an expert-level understanding of Geometric Dimensioning and Tolerancing (GD&T).
Program, set up, and operate CMMs and other automated inspection equipment to perform complex dimensional analysis on tools with tight tolerances.
Meticulously document inspection results, creating detailed reports that clearly identify any non-conformances, deviations, or areas for improvement.
Generate and maintain accurate and organized records of tool inspections, calibration activities, and non-conforming material reports (NCMRs) within the company's Quality Management System (QMS).
Conduct capability studies (e.g., Gage R&R) to assess the reliability and precision of measurement systems and tooling.
Collaborate directly with toolmakers, machinists, and engineers to diagnose and resolve dimensional and functional issues with tooling, providing clear data-driven feedback.
Manage the tool calibration program, ensuring all measurement and test equipment is calibrated on schedule and that records are accurately maintained per ISO/AS9100 standards.
Perform detailed surface finish and hardness testing on critical tool components to verify they meet material and processing requirements.
Create detailed inspection bubble drawings and comprehensive inspection plans for new tooling projects to establish clear quality standards from the outset.
Issue and track corrective action requests (CARs) related to tooling non-conformances, and follow up to verify the effectiveness of implemented solutions.
Conduct root cause analysis for tooling failures or production defects that are traced back to tool-related issues, using methodologies like 5-Why or fishbone diagrams.
Provide technical guidance and training to production staff and junior inspectors on proper measurement techniques and quality standards.
Approve or reject tooling based on inspection data and established quality criteria, and manage the disposition of non-conforming tools.
Participate in design review meetings for new tooling, offering valuable input on manufacturability and inspectability to prevent future quality issues.
Develop and optimize CMM and other inspection programs to improve efficiency, accuracy, and repeatability of the inspection process.
Perform reverse engineering of existing tools or components using 3D scanning equipment and CMMs to create CAD models for replication or modification.
Maintain a clean, organized, and safe work environment within the quality lab, adhering to all 5S and safety protocols.
Support internal and external audits by providing inspection records, calibration data, and demonstrating compliance with quality procedures.
Evaluate and approve tooling and fixtures from external suppliers, ensuring they meet all contractual and technical requirements before being integrated into production.

Secondary Functions

Collaborate with tooling engineers and designers to troubleshoot and resolve dimensional non-conformities found during inspection.
Assist in the development, documentation, and continuous improvement of inspection procedures, work instructions, and quality standards.
Maintain detailed and accurate inspection records, reports, and calibration logs within the designated quality management system (QMS).
Participate in cross-functional team meetings to provide data-driven insights on tool performance and quality trends.
