Experimental Study on the Inner Wall Ring Groove of 1J116 Soft Magnetic Alloy Based on Electrochemical Machining

Abstract

In this study, electrochemical processing was introduced into the inner wall ring groove of 1J116 soft magnetic alloy to obtain higher processing precision. A single factor experimental study was carried out for the processing and forming laws and mechanisms. The effects of pulse voltage, duty cycle, pulse frequency, and electrolyte pressure on material removal rate and groove width and groove depth of the inner wall were analyzed. The results show that the effects of pulse voltage, duty cycle, pulse frequency and inlet pressure on the material removal rate are positively correlated. The groove width and groove depth of the inner wall ring groove increase with the increase of process parameters, in order to achieve higher The processing accuracy requires a reasonable range of process parameters.
