A fatigue study was undertaken to determine how much the electrical discharge machine (EDM) process affected the fatigue life of balance materials by comparing EDM and regular milling machine samples. Simulation of a typical balance stress configuration was devised for the fatigue testing in order to obtain results more closely related to balance situations. The fatigue testing of the EDM and regular milling machine specimens to date has indicated that the EDM technique does reduce the fatigue life of the balance material 15-5PH steel, the first balance material tested. This conclusion was based on comparisons of the specimens' fatigue lives with theoretical and manufacturer's data. Hence, the EDM surface effects are detrimental to the fatigue life of this balance material. Future research areas and approaches are discussed.
