摘要
针对数控铣削加工网格时存在的刀具换向冲击问题,设计了两种刀轨,一种是兼容传统数控系统的直线圆弧拼接刀轨,另一种是在前种基础上改进的三次B样条曲线刀轨,分别适用于低速和中高速进给加工工况。以某工件的平面网格特征为例,详细介绍两种刀轨的快速计算生成方法。算法设计简单,程序运算量小,刀轨计算生成速度快。该思路对类似工件特征的刀轨设计计算具有普遍意义。
Two tool paths were generated to solve the inverting shock of the tool on the milling of the planar grids,one is the linear and circular matched path considering the traditional numerical control system,which is applicable to the low feed speed,the other is the third-order B-spline path,which is suitable for medium and high feed speed.Take the planar grids of a particular part for example,the generation method of the aforementioned two paths were discussed in detail.The proposed tool path generation method is characterized by its simple structure,small calculating amount and fast speed.It has a general performance for the path design of the parts with similar characteristics.
