摘要 为了保证数控加工中复杂曲线零件的车削加工精度,在普通二参数车削加工的基础上,提出了一种三参数路径规划车削插补算法。该算法将复杂曲面数控加工插补过程的路径规划分解为若干插补点之间的最优路径搜索和选取问题,根据不同加工要求设置决策变量,并进行取值判别,通过3个参数联动对曲线进行插补运算,优化加工过程中刀具的路径,并应用于相关的实例分析。研究结果表明,该优化算法能保证加工曲线的光滑性,有利于提高曲线的加工质量,并且该算法还具有计算规模小、求解迅速、数控加工插补误差小等优点。 Aiming at maintaining the machining accuracy of components with complex curve in CNC turning, a turning interpolation algorithm with three parameters path planning based on ordinary two parameters process was proposed. The interpolation process was decomposed into the optimal path searching and selecting problem between several interpolation points. Decision variable was set, value was discriminated ac- cording to the machining requirements, thus three parameters were integrated to achieve the interpolation of parts with complex curve, and adjustment of tool was accomplished. According to the related calculation examples, the results indicate that the smoothness of processing curve can be guaranteed through the proposed approach, and the machining quality is improved, also lower computational scale, smaller solu- tion time and less processing error are achieved.
