Abstract
A method of making a honeycomb die by using an electrode with parallel grooves in an electrical discharge machining process. The parallel grooves in the electrode are formed by a grinding wheel having a reverse tapered shape. The grinding wheel is progressively dressed during cutting of the parallel grooves.
