Title: 圧電セラミックス製の変換器を使用してワークピース切削加工を制御するための装置並びに方法
IPC: G05B19/404
Filed: 2007-02-02
Abstract: ワークピースの切削加工中に、切削工具に静的な負荷の他に、特に動的な負荷が作用する。このことは、ワークピースの損傷ひいてはその使用不能という可能性を伴って、結果的に切削部材の切刃におけるチッピング及びそれどころか切削部材の損壊に繋がる。さらに曲げ・ねじり力が切削工具に作用し、工作機械に負荷をかけ、結果的にワークピースの誤った加工を伴う切削工具のポジション変化をもたらす。さらに振動及びチャタリングはワークピース加工を損なう。従って本発明によれば圧電セラミックス製の変換器（２０，３０）が、切削工具（３）の領域に配置されていて、そこで切削合力の力コンポーネントが変換器に作用する。変換器に作用する力により形成された信号は、工作機械の制御装置に伝送され、この信号を考慮してワークピースの加工は制御される。
