MDI

On the shop floor, MDI can be understood as: Manual Data Input mode for temporary commands. It ties machine kinematics directly to geometric accuracy and surface consistency. Managed well, it improves process repeatability and lowers correction workload. Use first-article evidence and trend data to keep this item stable over time.

Impact on Results

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

Implementation Points

• Keep axis diagnostics snapshots for first article and end-of-shift comparison.
• Confirm home return consistency before unattended operation.
• Verify backlash and warm-up behavior before locking production offsets.

Troubleshooting Signals

Motion instability is often mistaken for tooling trouble, so verify machine dynamics first. Thermal state changes can shift behavior even when programs and offsets stay the same.

Verification Checklist

• Recheck compensation values after alarm-driven restarts.
• Record machine thermal condition when dimensional drift appears.
• Trend repeatability at fixed checkpoints during long cycles.
