Cathode and its Feeding Path Design in the NC-ECM Process of the Rimed Integral Impeller

Abstract:

Article Preview

At present, the rimed integral impeller is machined mainly by NC-electro-discharge machining (NC-EDM). To raise the efficiency of EDM process, the pre-channel is machined by NC-ECM to replace NC-EDM in rough machining process. The experimental results indicate that the whole process efficiency can be improved by not less than 20%, but the design of cathode and its feeding path in NC-ECM is a skilled and costly work. To improve machining accuracy and simplify design process, a new design approach based on simulating the shaping process of NC-ECM was put forward to design the cathode and its feeding path.
