刀具磨损补偿

定义

修正刀具磨损造成的偏差。

以前置元数据中的定义作为统一语义，并在装夹、加工与检验环节保持一致。

公式/规则

• 刀具磨损补偿应依据测量漂移更新，而不是只凭表面状态主观调整。
• 每次只做可追溯的小步修正，并记录刀号、补偿号和测量误差。

典型范围

• 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.

现场场景

• 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.

常见错误/排障

• 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.
