开式整体叶轮加工关键工艺技术研究

摘要

The geometric characteristics of parts and processing difficulties are analyzed. The key technologies for the rough and the finishing is presented. The key technologies for building of the leaf ruled envelope surface and choice of tool axis vector in plunge mill rough process,the whole leaf processing cutting tool path planning using the parameters method in the finishing process are described. By using software VERICUT,a machining simulation verification was made. The open impeller machining the whole process examples are completed.%首先分析了该类零件的几何特点以及加工难点,然后提出了粗加工以及精加工当中的关键技术.阐述了插铣粗加工中,有关叶片直纹包络面的构建,刀轴矢量的选择;精加工中叶片整体加工中使用参数法规划均匀的刀具切削轨迹等关键技术.最后利用VERICUT软件,进行了加工仿真的验证,并且加工完成了开式整体叶轮的加工实例.
