Research on Vector Optimization Method of NC Axes for Complicated Surfaces and Five Axes

科学技术的快速发展,为复杂曲面五轴加工方式的不断优化提供了必要的技术支持,使得其加工技术水平逐渐提升。实践过程中加工人员在曲面形状突变及干涉情况时,若采用五轴加工轨迹生成方法,由于其中刀轴矢量剧烈变化的问题,使得刀具性能受到了潜在威胁,且产品加工质量难以保障。针对这种情况,应加强与之相关的五轴加工刀轴矢量优化方法使用。基于此,本文将对复杂曲面五轴数控加工刀轴矢量优化方法进行系统阐述。

The rapid development of science and technology has provided the necessary technical support for the continuous optimization of five-axis machining of complex curved surfaces,which has led to the gradual improvement of its processing technology. In the process of practice,when the surface shape is abruptly changed and the interference happens,if the machining method of five-axis machining path is used,the tool＇s performance is under the potential threat because of the sharp change of the vector of cutter shaft,and the processing quality of the product is hard to guarantee. In view of this situation,we should strengthen the related five-axis tool axis vector optimization method. Based on this,this paper will systematically elaborate the vector optimization method of tool axis of five-axis NC machining of complex surface.
