Knowledge-Based System for Wire EDM

The paper proposes an all-round solution to a number of problems, related to the wire-EDM process. The solution is based on the development of a Knowledge-based system. It enables process monitoring and control, making use of a reliable rupture probability parameter. An expert system for operator assistance, fault diagnosis and training is also included. Machine settings are determined automatically by means of a work-preparation module. Experiential and theoretical knowledge about the process is stored in separate knowledge bases.
