摘要 考虑主轴偏心 ,基于周铣过程中刀具切削刃上任意点与工件相对运动的轨迹方程和周铣过程几何特征 ,构造出可以求解周铣加工表面上任意一点形貌高度值的三维表面形貌仿真算法 ,并给出了相应的仿真算例。该算法无需对刀齿进行微段离散 ,并且不依赖于工件网格划分 ,加工表面上任意一点形貌高度值的计算次数等于刀具齿数 ,具有通用性好、运算速度快、结果准确度高的特点。 Simulating machined surface topography is very critical since it affects directly the surface quality, especially the surface roughness. Based on the trajectory equation of the cutting edge relative to the workpiece and the geometrical characteristics of the end milling process, a new method for the prediction of the topography of the generated surface is developed. With the method, it is unnecessary to discretize the cutting edge and mesh the workpiece, the topography values of any points on the surface of the workpiece can be calculated, and the cutter runout can be taken into account. For any point, the number of calculations is equal to the number of cutter teeth. Numerical results indicate that the algorithm is general, efficient and of high precision.
