| 摘 要： | 在综合考虑刀具几何参数，刀具振动和最小切削厚度等因素对已加工表面形貌影响的前提下编写了表面微观形貌的仿真程序，在仿真时把一个随机振动信号成功地叠加在理论表面粗糙度中。提出一种建立圆弧刃金刚石车刀超精密车削表面粗糙度模型的新方法。结果表明，仿真得到的表面微观形貌，能够比较正确地反映出超精密加工将要获得的表面轮廓。

| Abstract: | The tool sharpness can influence material removal and surface finish through the minimum thickness of cut in ultraprecision turning. A surface micro-topography simulation program is developed,in which the effects of tool geometry,machine tool vibration and minimum thickness of cut on surface micro-topography are considered,a random motion signal is incorporating into the theoretical analysis of surface generation. A new surface roughness model based on cutting geometry for diamond turning with a round nose tool is proposed. The results show that the surface micro-topography simulation program can properly simulate the surface profile generated in ultraprecision turning operations. |
