Dec 01, 1999· GRAPHITE IS UNFORGIVING. Graphite is unforgiving of surface defects, reflecting even the smallest flaws quite clearly in the workpiece. As such, a good surface finish on the electrode before die sinking reduces bench time on the tool after. A fine step over, and small chordal deviation used to optimize surface finish give good results.
