The purpose of this research paper is to apply the principle and technique of Fuzzy Analytical Hierarchy Process (FAHP) to obtain the weights of materials machinability in Electrical Discharge Machining (EDM) process, with the appropriate parameters concerning the process depending on their dielectric medium used in the process. FAHP is a powerful and flexible tool for multiple attribute decision making method to get priorities and take the best decision when different aspects of a decision need to be considered. It is known that EDM is a manufacturing process that is based on thermal erosion due to the plasma channel formed between the work piece and the work tool formed in the dielectric during the electrical discharge.
