| 摘 要： | 超精密车削加工中,影响工件表面形貌的主要因素有刀具的几何形状、进给速度、主轴转速、刀具与工件的相对振动等,考虑这些因素,对超精密加工的三维表面形貌进行建模,并通过仿真分析刀具轮廓在工件径向截面内可能发生的剪切现象。验证结果表明,用该模型仿真超精密端面车削的工件表面能得到较好的效果。利用该模型可以模拟刀具切削运动的轨迹、预测工件表面三维微观形貌及二维截面轮廓形状等表面特征,并可将其作为实际切削加工中切削参数优化的理论指导。

| Abstract: | In ultra-precision machining,the major factors influencing the surface topography of workpieces include many parameters of cutting process such as the tool geometry,feed rate,the speed of spindle and relative vibration between the tool and the workpiece.A surface topography simulation model of ultra-precision machining is established considering these factors.Trimming phenomenon of the tool edge profile is also analyzed at the radial section of the workpiece by the simulation program.It is experimentally shown that good effect is obtained by using the model to simulate the surface topography of ultra-precision face turning.The model can also be used for simulating the traces of tool motion,predicting the three-dimension microscopic surface topography and two-dimension section profile,and optimizing the cutting parameter for diamond turning process. |
