| 摘 要： | 由于整体叶轮的叶片是扭曲的,在建模和加工方面都有极大的困难。相比三轴加工机床,五轴机床具有较高的生产率和较好的加工质量等优点。根据实际工程数据,选用Pro/Engineer软件对实体叶轮进行造型,并对整体叶轮数控加工的走刀路径进行了分析和研究,针对干涉问题,选取刀轴自动避让功能,并定义刀轴限界功能。成功将NC程序从Powermill软件中导入到DEMAGE五轴机床。并以某离心式压缩机整体叶轮产品为例进行了加工验证,加工出了实体产品。实验结果表明选用的加工方法和工艺是非常成功的。

| Abstract: | Impeller is very difficult to machine and model because of the twisted blades. Comparing with three-axis machining, five-axis machining offers advantages such as higher productivity and better machining quality. Based on the actual engineering data, pro/Engineer software is applied to produce three-dimensional geometric model of the integrated impeller. Furthermore, analysis and research were made for tool path of the integrated impeller machining. Tool axis automatically avoiding function was adopted, and ... |
