Feed Hold (Fault Response)

For CNC teams, Feed Hold (Fault Response) points to this concept: Pauses feed to handle abnormal conditions. A disciplined response prevents repeating the same stop condition. It delivers the best results when programming, setup, and inspection use the same assumptions. State clarity is critical here: test safe blocks and resume behavior before release.

Implementation Points

• Re-verify safety functions after electrical or control service.
• Capture alarm context before reset: code, axis state, and recent blocks.
• Check interlock and sensor chain before changing control parameters.
• Use a written recovery SOP with restart verification steps.

On-Machine Signals

• Different alarms triggered by same process step
• Recovery success depending on operator sequence
• Fault timing clustered around one operation

Typical Pitfalls

Repeated alarms often involve process triggers, not only hardware failure. Temporary bypasses become long-term risk when closure is not tracked.

How Teams Standardize It

Teams usually stabilize this area by treating alarm logs as process data, not only maintenance data.

• 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.
