Hole Enlarging

In practical manufacturing terms, Hole Enlarging describes: Increasing the diameter of an existing hole. It shapes load transitions, chip evacuation, and final feature quality. Documented ownership of this item prevents many late-stage adjustments. Its best results come from disciplined execution across shifts, machines, and operators.

Impact on Results

Treat this as part of an integrated process chain rather than a standalone parameter. That approach reduces trial-and-error and speeds up reliable release.

How to Apply It

• Confirm chip evacuation before increasing material removal rate.
• Simulate holder clearance and non-cutting travel with real setup limits.
• Segment complex operations for safer prove-out and restart.

On-Machine Signals

• Localized chatter at entry or corner segments
• Cycle time loss dominated by non-cutting moves
• Tool load spikes on path transitions

Failure Modes

Poorly defined restart points increase scrap risk after interruptions. CAM-efficient paths can still be unstable at the machine without transition control.

Audit Points

• Capture proven strategy parameters for reuse.
• Review engagement map at high-load regions.
• Verify clearance and retract planes against fixture height.
