公式/ルール

• 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.

代表的な範囲

• 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.

現場シナリオ

• 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.

よくある問題/トラブルシュート

• 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.
