基于PowerMILL和CATIA的叶轮五轴联动高速加工技术研究

Research on Power Mill and CATIA for 5-axis HSM Technology of Impeller

根据典型的通道类零件叶轮的结构特征,首先利用CATIA的混合建模技术对其进行了详细设计,然后根据Power MILL对叶轮五轴联动加工方案进行了深入研究,产生了深窄槽道和大扭角的加工轨迹,最后在优龙五轴联动加工中心上进行加工,验证该叶轮加工方案的可行性,加工程序的正确性。通过仿真和实际加工结果表明,该叶轮完全满足使用要求。

According to the structural characteristics of impeller of the aisle parts, firstly, the impeller is designed by CATIA hybrid modeling technology, secondly, the five-axis high-speed machining strategies is deeply researched according to Power MILL, the tool-path of deep narrow channel and large twist angle is produced, and finally the processing is conducted in HURONK five-axis machining center,and the feasibility of the impeller machining scheme and the correctness of processing program are verified. The detection and actual processing results show that the impeller can fulfill the using requirement.
