Single Block

During CNC planning and execution, Single Block denotes: Mode that executes the program block by block. A disciplined response prevents repeating the same stop condition. Treating it as controlled process data reduces shift-to-shift variation. Treat this as part of program-state control, not just line-by-line syntax.

Where It Shows Up

This item performs best when programming, setup, and quality teams review it together. Cross-functional control is what keeps results repeatable after handoffs.

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.

Risk Focus

Fast reset culture hides intermittent faults and increases safety exposure. Repeated alarms often involve process triggers, not only hardware failure.

Validation Routine

• Verify tool and position state before cycle resume.
• Document corrective action and recurrence outcome.
• Separate electrical, mechanical, and program evidence.
