Work Coordinate Measurement

From a process perspective, Work Coordinate Measurement refers to: Measuring positions in the work coordinate system. When this chain is wrong, cutting can be wrong even if every single number looks valid. Consistent handling of this concept is a strong predictor of first-pass success. Coordinate-chain integrity is the key control point when setups are repeated across fixtures.

Control Actions

• Probe key datums after reclamp and compare with expected offset stack.
• Lock proven offset pages before batch release.
• Use clear naming for pallet or fixture-specific coordinate groups.
• Simulate with the same active coordinate chain used at the control.

On-Machine Signals

• Uniform part shift across all features
• Correct shape but wrong global location
• Different results between pallets with same program

Troubleshooting Signals

Coordinate mistakes often survive simulation when setup assumptions differ from reality. Untracked manual edits can invalidate an otherwise stable process.

Scaling to Batch Production

Teams usually stabilize this area by maintaining one authoritative setup reference per fixture.

• 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.
