对透平叶轮多坐标数控加工中进、出口边缘修圆技术进行了研究 ,在分析圆角构成的基础上 ,对各圆角类型进行几何构造 ,既而提出用平底棒铣刀侧铣加工外延及缩进的多段圆弧型或椭圆弧型圆角的刀位轨迹生成算法 ,有效地解决了叶轮类零件数控加工中的修圆问题 ,为透平叶轮CAM软件的编制提供了有效途径 ,该方法已在自行研制的ICAM系统中得到了成功应用
Based on the analysis of the fillet structure, the geometrical structure of each fillet type was studied. The extension of the side milling machining with flat-bottom bar milling cutter Indenting multi-segment circular arc or elliptic arc-shaped tool path trajectory generation algorithm to effectively solve the round parts of the CNC machining rounding problem for turbine turbine CAM software provides an effective way to compile this method Has been successfully developed in the ICAM system has been successfully applied
