Abstract : An analytical derivation is presented of mechanisms which govern the advancement rate of the interaction front of an electrode tool and the work piece in electroerosion machining, with particular applicability to tool wear and its effect on the shape and dimensional accuracy of machined cavities. Analysis showed that during the machining of a cavity, the current density depends on both the angle between the direction of feed and a normal to the electrode tool surface, and on the curvature at a given point. Maximum current density occurs at that point where a normal to the tool surface is parallel to the direction of tool feed. Using special equipment, current density for various spectors of the interaction front of electrodes was determined previously. The experimental data, with an error of no more than 7 percent, confirms the validity of the relationship derived for current density. (Author)
