Abstract
The electric field or current density distribution around a diamond particle embedded in a metal anode during electrolytic in-processing dressing (ELID) is calculated for the two-dimensional case of a long diamond particle without protrusion and for a periodic array of such long, parallel particles. It is found that there is a field concentration at the diamond/metal boundary so that the metal dissolution rate is the largest at such boundary. For the periodic array, the average current density is independent of the diamond concentration so that the metal dissolution rate increases with increasing diamond concentration. Hence, for the same ELID effect, the current required for a high diamond concentration tool is less than that required for a low diamond concentration tool.
