摘      要：Electrochemical machining(ECM)is an economical and effective method for blisk manufacturing and includes two steps:channel machining and profile *** allowance distribution after the channel machining will directly affect the profile ***,to improve the uniformity of allowance distribution in the machining of channels,a method that incorporates a variable feed rate mode is *** the machining process,the feed rates are dynamically changed according to the needs of the side gap at the different feed *** a result,the side gaps at the different feed depths vary,contributing to a decrease in the allowance *** this study,the dissolution processes of a blisk channel are simulated using different feed rates,and prediction profiles are *** on the prediction profiles,the relationship among the feed rate,feed depth,and side gap is ***,the feed rates at different feed depths are adjusted according to the *** addition,contrast experiments are *** with blisk channel ECM using a constant feed rate of 1 mm/min,using the variable feed rate decreases the allowance differences in the convex and concave parts by 62.2%and 67.4%,*** indicates that using the variable feed rate in the ECM process for a blisk channel is feasible and efficient.
