金属切削%受迫振动
金屬切削%受迫振動
금속절삭%수박진동
Metalcutting%ForcedVibration
金属切削振纹的产生,大致区分为两种,一为独立于刀具与工件组成系统之外的受迫振动引起,二为刀具与工件之间的自激振动。本文主要阐述前者产生振动而引起的振纹,在机床切削过程中,受迫振动主要来自传动系统和工件旋转本身。
金屬切削振紋的產生,大緻區分為兩種,一為獨立于刀具與工件組成繫統之外的受迫振動引起,二為刀具與工件之間的自激振動。本文主要闡述前者產生振動而引起的振紋,在機床切削過程中,受迫振動主要來自傳動繫統和工件鏇轉本身。

There are approximately two reasons that result in chatter marks in metal cutting. One is forced vibration which is independent of the system of the cutter and workpiece,the other is self-excited vibration between the cutter and the workpiece.This article mainly studies the former. In the cutting process of the machine tool, forced vibration comes mostly from mechanical drive system and the revolving workpiece itself.
