摘要
探讨了细分曲面五轴数控加工基础技术。以Catmull-Clark细分曲面为研究目标,首先讨论细分曲面顶点法矢量计算及等距面实现,然后建立细分曲面粗加工模型;其次对该模型采用环形刀刀轴矢量按曲面法线导动方式进行五轴数控加工,推导了刀具姿态、切削半径及刀位轨迹生成计算,最后给出了计算机仿真的实例。
Basic research for five-axis NC machining of subdivision surface is presented.Research on Catmull-Clark subdivision surface,the normal vector of subdivision surface vertex and the offset surface calculation are discussed firstly,then the rough machining model of subdivision surface is built and machined by using five-axis machining with the motion of the torus end-mill position and orientation according to the normal line of surface.The tool position and orientation,cutting radius and cutter location path are calculated.Finally a computer simulation instantiation is given.
