大直径三元叶轮加工工艺的改进

Improvement on Machining Technology of 3-D Impeller with Major Diameter and Its Application

简要介绍了大直径、宽深流道直纹面三元流叶轮的一种高效数控加工方法。该法在对叶轮流道进行数控粗加工时,可以快速除去毛坯流道材料,提高流道粗加工的材料去除率。

This paper mainly introduces a high-efficient numerical-control machining method for major diameter deep flow channel of 3-D impeller with ruled-surface. The method can rapidly remove rough materials and improve the removal rate for material when the rough machining with numerical-control is carried out on channels of impeller.
