刀具移距在诱导轮叶片加工中的作用

通过数学方法，推导出诱导轮铣加工叶片时刀具移距的计算公式，解决了诱导轮叶片加工过程中产生根切、顶切的问题。以某型号发动机涡轮泵诱导轮为例，给出了工艺流程和加工参数。加工出的产品经水力试验和地面热试车及飞行考验，完全满足设计要求，表明该工艺方法正确，工艺参数可行有效。该工艺技术还可推广用于航空、航天以及民用涡轮泵诱导轮的...

Application of cutter travel distance in inducer blade milling

The calculation formula of cutter tranvel distance during inducer blade milling was derived by mathematic method.It solved the problems of undercutting and top-cutting in the process of inducer blade milling.Taking the inducer of turbopump in a certain space engine for example,the process flow and machining parameters of the inducer are presented.The product made with the proposed process and parameters was proved through hydraulic test,ground hot firing and flight mission.The results indicate that the prod...
