Electromechanical grinding at high work feed rate
1988
Abstract Electromechanical grinding (EMG) of alloy tool steel and some other alloys was investigated at a higher work feed rate than that used in electrochemical grinding (ECG), with particular consideration of grinding mechanisms. An experimental analysis of grinding forces reduced by applied electrolytic action showed a slight decrease in mechanical removal and a severe loss of mechanical properties. Additional contributions of the electrolytic action to a reduction of grinding forces were clarified as the preferential dissolution of the hardened second phase and the suppression of the frictional component of grinding forces between material and wear flats. Theoretical consideration of the electrolytic action suggested an appropriate grinding mechanism on the basis of the experimental results.
