摘要: 金属切削振动中现行的切痕形成机理把切痕看成是刀具——工件之间相对振动的简单再现,按照这种机理来分析机床——刀具——工件系统的动态特征往往使研究工作者陷入错误的结论或引起混乱。本文指出由于刀具付切削刃对工件表面前几转形成的切痕进行重复切削,切痕形成的机理比现行的简单再现机理复杂,因而提出一种新的概念来阐明切痕形成的机理可以为解决切削振动中某些关键问题提供正确的途径。

Abstract: In the conventional theory, the mechanism of cutting marks formation in metal cutting Vibration has been treated as a simple repro-duction of tool-work vibration. However, such theory may mislead researchers into wrong concclusions and thus create confusion; In this article a new concept is introdued which deals, we think, more adequately with this problem than the convensional theory.
