【摘要】：为避免薄壁深腔零件侧壁加工过程中因铣削力引起的让刀变形而导致加工精度较低的问题,提出一种基于有限元的铣削加工误差仿真算法。考虑工件/刀具系统的让刀变形及工件的回弹变形,计算生成刀齿微元的连续运动轨迹,并基于点的六面体映射算法对材料进行去除,从而得到连续加工过程和加工面上任意点的加工误差及加工面形貌。以某典型薄壁深腔开口框体结构为加工对象进行了仿真分析,通过实验验证了所提仿真方法的准确性。
[Abstract]:In order to avoid the problem of low machining precision caused by the cutting force caused by milling force in the machining process of thin and deep cavity parts, a simulation algorithm based on finite element method for milling machining error is proposed. The point's hexahedral mapping algorithm is used to remove the material, thus the machining error and the surface morphology of any point on the machining surface are obtained. A typical thin-walled and deep cavity opening frame structure is used to simulate the machining object. The accuracy of the proposed simulation method is verified by the experiment.
