Position Compensation

From a process perspective, Position Compensation refers to: Compensation used to correct positioning error. Measurement discipline prevents offset drift from becoming hidden scrap risk. Consistent handling of this concept is a strong predictor of first-pass success. Separate base geometry correction from wear correction to keep adjustments interpretable.

Operational Value

Do not tune this in isolation. Stable outcomes come from balancing machine behavior, fixturing response, and metrology feedback at the same time.

Practical Controls

• Recalibrate after collision, thermal shock, or major setup changes.
• Log compensation edits with time and operator traceability.
• Validate probe repeatability across multiple approach directions.

On-Machine Signals

• First-part pass but later drift in same batch
• Frequent manual correction on same feature
• Calibration status unclear at shift handoff

Stability Risks

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

Before-Run Checks

• Verify calibration status and due dates for all key instruments.
• Audit offset tables for unexpected edits before cycle start.
• Re-run reference checks after warm-up and after long idle.
