Tool Wear Compensation

Definition

Corrects deviation caused by tool wear.

Use the frontmatter definition as the controlled meaning for setup, machining, and inspection decisions.

Formula / Rule

• Update wear offsets from measured drift instead of guessing from surface quality alone.
• Apply small, traceable corrections and record the tool, offset number, and measured error each time.

Typical Range

• Most corrections should stay small and measurable; large jumps usually mean measurement or process instability.
• Compare wear trend by part count or cutting time, not by isolated operator impression.

Shop-floor Scenarios

• Adjust wear compensation after first-article measurement instead of editing the base geometry offset.
• Use measured drift over several parts to decide whether compensation or tool replacement is the better action.

Common Errors / Troubleshooting

• If compensation keeps growing fast, inspect tool wear mode and workholding stability instead of adding larger offsets forever.
• If one correction flips size in the opposite direction, verify the offset sign and the axis/tool orientation.
