What is On-Machine Inspection?
On-Machine Inspection (OMI) is the process of measuring a machined part while it remains on the CNC machine. With NC-PartLocator, manufacturers can verify tolerances immediately, avoiding delays and wasted time. This ensures that parts are checked before removal from fixtures, preventing downstream issues.
Why Use NC-PartLocator for On-Machine Inspection
- Immediate Insight: Operators can confirm if a part will pass final inspection without removing it from the machine.
- Reduced Reliance on CMMs: Backlogs at Coordinate Measuring Machines are minimized, speeding up workflow.
- Cost Savings on Large Parts: There is no need for oversized CMMs or expensive portable and laser systems.
- Early Error Detection: Fixture movement, tool wear, and machine drift can be identified before they cause major issues.
Key Features of NC-PartLocator
- On-Machine Verification: Parts are inspected directly after machining.
- Process Adaptability: Production continues smoothly while checks are performed.
- Large Part Capability: Parts that cannot fit on existing CMMs can still be measured accurately.
- Corrective Insights: The system highlights whether errors originate from fixtures, tools, or the machine itself.
Benefits for Manufacturers
Using NC-PartLocator for on-machine inspection brings measurable improvements:
- Eliminates long waits for CMM availability.
- Utilizes existing CNC machines for inspection tasks.
- Accelerates overall production times.
- Strengthens quality control within production rather than relying solely on Quality departments.
Industries That Benefit Most
This technology supports multiple industries where precision is critical:
- Aerospace
- Motorsport
- Marine
- Castings and forgings
- Space technology
- Composites manufacturing
How the Process Works
- The part is machined as usual.
- NC-PartLocator measures the part while it remains mounted on the CNC machine.
- The system evaluates potential error sources, such as tool wear or machine misalignment.
- If any tolerance issues appear, corrections are made immediately before waste occurs.
Proven Results in Real-World Use
- One manufacturer reported their parts are now “10 times better” compared to their previous supplier.
- A Formula 1 team cut part setup times by over 9 hours, significantly improving efficiency.
- Another company increased weekly output by seven times after adopting this technology.
Best Practices for Implementation
- Provide operator training for seamless adoption.
- Integrate inspection steps into existing machining processes.
- Regularly calibrate tools and fixtures.
- Use inspection feedback to refine and optimize production strategies.
Conclusion
On-machine inspection with NC-PartLocator delivers precision, speed, and reliability. It reduces downtime, lowers costs, and provides consistent quality improvements. Manufacturers working with large, complex, or high-value parts gain a clear advantage by adopting this system. As industries demand greater efficiency and accuracy, this approach ensures consistent success on the production floor.
