Production Engineering Technician - CNC Program Prove-Out, CAM Optimization & ISIR Support

Production Engineering Technician – CNC Program Prove-Out, CAM Optimization & ISIR Support The Production Engineering Technician is responsible for proving out new CNC programs, performing CAM adjustments using hyperMILL and VeriCut, ensuring parts successfully meet ISIR (Initial Sample Inspection Report) requirements prior to production release. This role ensures brake and clutch components are machined safely, efficiently, and in full compliance with engineering specifications and customer quality standards. The technician plays a critical role in new product introduction (NPI), engineering changes, and automotive quality compliance. Key Responsibilities CNC Program Prove-Out & Optimization Prove out new CNC programs on multi-axis machining centres (mainly 5axis) Set up first-article and initial sample runs Validate tooling, fixtures, work holding, offsets, and program parameters Identify and correct programming errors or interference risks Make CAM toolpath adjustments and strategy improvements in hyperMILL Optimize feeds, speeds, and tool engagement for cast iron and aluminium components Reduce cycle time while maintaining dimensional stability and surface finish quality ISIR / Quality Validation Ensure first-run parts meet ISIR requirements before production release Verify all dimensions, tolerances, and GD&T callouts per engineering drawings Support dimensional layout inspections using precision measuring tools. Collaborate with Quality to compile inspection data and resolve non-conformances Address root causes of dimensional variation, surface defects, or process instability Implement corrective actions prior to customer submission Troubleshoot machining issues (chatter, runout, tool wear, thermal growth) Improve process repeatability and performance Document setup sheets, tooling lists, and process revisions Provide feedback to Production Engineers about improvements Train operators on finalized programs and standardized setups Reduce scrap, rework, and downtime Required Qualifications 3–5+ years of CNC machining experience in a production environment Experience proving out CNC programs for precision-machined components Hands‑on experience supporting ISIR or PPAP submissions Working knowledge of G‑code and M‑code Experience making CAM adjustments in hyperMILL Strong understanding of GD&T and drawing interpretation Experience machining cast iron and aluminium components Preferred Skills Experience in automotive brake or clutch component manufacturing Multi‑axis machining experience Familiarity with low‑volume manufacturing environments Root cause analysis and corrective action experience Hours Monday – Thursday 8am – 5pm and Friday 8am – 1pm. #J-18808-Ljbffr Alcon Components Ltd
