Paper Title:
Precise Numerical Control Electrochemical Machining for Integral Impeller with the Adding Wobbly Feeds
  Abstract

Lots of integral impellers are used in the new kinds of jets. The jet engine weight can be lightened much, and the thrust,work life and the safety coefficient can be increased remarkably. Based on the integral impeller’s structure features and the processing difficulties with special complex blades, the shaping law on electrochemical contour evolution machining the blades is analyzed and studied, the multi-axis linkage movement feed tracks are designed optimum by the shaping laws and the tests. The combined cathode with the reasonable flowing fields is designed, there is an eccentric between the cathode sole plate and cathode body, the bidirectional feeds method is adopted, the short circuit and electro-discharged sparks damages are eliminated. The redundant rests in blades back is removed by adding wobbly feeds. Machining tests are carried out. The blades satisfying precision are produced.
