摘　　要：为提高整体叶轮的加工质量,解决整体叶轮五轴联动加工程序编程复杂、验证困难,易出现干涉、碰刀等问题,文章在分析整体叶轮结构、加工难点的基础上,对机床的选用,工装夹具的确定,刀具的选择,CAD/CAM软件的确定以及加工工艺的规划等方面,进行深入研究与探讨。根据Mikron_UCP_800Duro机床技术参数,利用VERICUT多轴数控仿真软件平台,构建了虚拟的真实五轴联动数控机床的运行环境,实现了对叶轮各加工工序NC程序的正确性、可靠性的虚拟仿真与验证。最后,在Mikron_UCP_800Duro五轴加工中心上,完成了对整体叶轮的实体加工,无任何刀具干涉、碰撞等现象,加工精度满足性能要求,对类似的叶轮加工具有很好的借鉴作用。In order to improve the machining quality of integral impeller,solve five axis machining programming is complex and difficult to validate,prone to interference and touch,the paper makes deep research and discussion in the five-axis machining technology including the cutting machine's selection,determination of jig and fixture,tool selection,CAD/CAM softw are and process planning based on the analysis of the integral impeller structure and machining difficulties. Using VERICUT multi axis NC simulation softw are,the virtual five-axis NC machine tool w as constructed according to the technical parameters of M ikron_UCP_800 Duro,and verified the NC program,then completed the solid impeller machining that accuracy meets performance requirements on the M ikron_UCP_800 Duro five axis machining center w ithout any interference or collision phenomenon. It has a good reference for processing similar impeller.
