Experimental Investigation on AECM of High Speed Steel

Abstract

Abrasive electrochemical machining (AECM) is a complex technological method used for machining hard materials. This method is based on a combination of mechanic, electric and chemical factors. Present paper presents the results of experimental researches accomplished by authors in order to determine the influence of main working parameters (such as voltage, abrasive wheel speed, longitudinal feeding rate, contact pressure) upon performances of electrochemical grinding (total amount of removed material, roughness of machined surfaces, radius of edge roundness) of high speed steel.
