Repeatability

In production use, Repeatability is commonly defined as: Accuracy of repeatedly returning to the same position. Measurement discipline prevents offset drift from becoming hidden scrap risk. Consistent handling of this concept is a strong predictor of first-pass success. Its best results come from disciplined execution across shifts, machines, and operators.

How to Apply It

• Validate probe repeatability across multiple approach directions.
• Cross-check machine and bench measurements on sentinel features.
• Use traceable masters and verify instrument condition before each shift.
• Separate wear compensation from geometric base-offset updates.

On-Machine Signals

• Offset updates increasing faster than normal wear
• Mismatch between probe and bench measurements
• First-part pass but later drift in same batch

Troubleshooting Signals

Measurement bias grows when environment and sequence control are weak. Stale compensation tables can look stable until a process change exposes them.

Scaling to Batch Production

Teams usually stabilize this area by separating compensation responsibilities by type.

• Keep setup records and inspection evidence linked to each process revision.
• Re-validate after tooling, fixture, or control-logic changes.
• Use first-article and restart checks as mandatory release gates.
