| Abstract: | In order to solve the problem of finishing the blade surface of integral impeller,the research on mechanism of 5-axis numerically controlled electrochemical contour evolution grinding(NC-ECCEG) is being carried on.Electrode reaction of NC-ECCEG and forming law of numerically controlled electrochemical contour evolution machining(NCECCEM) were analyzed.On the basis of technological tests of NCECCEG,the term of critical contour evolution speed was defined. The forming law of NC-ECCEG was discovered.A series of technical problems were solved.Finally,a qualified integral impeller has been machined.The machining efficiency of NC-ECCEG can be 12 or more times better than that of manual polishing operations. |
