| Abstract: | In order to solve the problem of machining the blade surface of an integral impeller,the paper carried out the research on the mechanisms of electrochemical contour evolution grinding(ECEG).The electrode reaction of the ECEG and the formation law of electrochemical contour evolution machining(ECEM) were analyzed.Through technological tests of the ECEG,the concept of critical contour evolution speed was defined,the formation law of ECEG was discovered,and a series of technical problems were solved.Finally,a qualified integral impeller was machined.The machining efficiency of ECEG can be 12 or more times better than that of manual polishing. |
| Keywords: | electrochemical grinding integral impeller machining mechanism |
