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。
In diamond ultra-precision turning, the inevitable vibration between the tool and the workpiece, thus affecting the surface quality of the workpiece. In this paper, the three-dimensional topography of the workpiece surface under the condition of vibration is simulated and the cross-sectional profile of the workpiece surface topography in the radial, circumferential and tool helical path directions is theoretically analyzed. The results show that the different cross-sections have Different characteristics of the information, and according to the simulation of the workpiece surface three-dimensional topography data were vibration identification.
