摘要

在金刚石超精密车削加工中

刀具与工件之间不可避免地存在一定的振动

从而影响工件表面质量.本文对在具有振动情况下工件表面的三维形貌进行了仿真

并从理论上对工件表面形貌的径向、周向与刀具螺旋轨迹方向的截面轮廓进行了分析

结果表明不同的截面具有不同的信息特征

并据此对仿真得到的工件表面三维形貌数据进行了振动辨识.

Abstract

In diamond ultra-precision turning

there is unavoidably

a relative vibration between the tool and the workpiece

which influences the quality of workpiece surface. This paper simulates the influence of relative vibration between the tool and the workpiece

and theoretically analyzes the profile of radial section

circumferential section and spiral section along tool motion. The results show that different section possesses different characteristics. On the basis of analytical results

the article identifies the relative vibration between the tool and the workpiece through the data of three-dimensional topography obtained from the simulating model.
