• Comply with all Health & Safety and Environmental policies and regulations. Proactively identify hazards and promote a safe, sustainable work environment.
• Develop CMM inspection programs and methodologies for New Product Introductions (NPI), including fixture design, gauging identification, probing strategies, and alignment routines to ensure accurate and repeatable measurements.
• Create, test, and optimise existing inspection CMM programs using PC-DMIS & Calypso preferably, alternative software will be considered.
• Support the first article, in-process, and final inspections to ensure components meet customer specifications.
• Apply GD&T principles and interpret engineering drawings and 3D CAD models accurately.
• Generate detailed inspection reports and maintain records for traceability and audits.
• Document non-conformances and support continuous Improvement initiatives / cost reduction activity of manufacturing processes.
• Support Cost estimations through detailed analysis from a quality aspect.
• Technical support / troubleshooting of shop floor CMM’s.
• Support investigations / Root Cause Analysis for any defective part and implementing corrective actions, following a systematic approach within a cross functional team.
• Liaise with customers on drawing updates and change requests from a dimensional and inspection methodology.
• Conduct capability analyses (e.g., Cp, Cpk) of production processes to assess measurement system performance and ensure process stability and compliance with quality standards
• Utilise SPC tools, including run charts and control charts, to monitor process performance, identify trends, and support data-driven decision-making for continuous improvement.
• Training operators or inspectors on inspection equipment and procedures.
• Support quality certification efforts by preparing and participating in audits, ensuring compliance with standards and implementing corrective actions based on audit findings.
• Ensure all CMM programs, probe configurations, and inspection documentation are finalised, version-controlled, and ready for production handover.
