Based Cad / Cam System Edm Milling Process

In conventional EDM, it takes long time and high expense to fabricate electrodes. Though the investigation on EDM process and EDMMi1I method, A post-process program for EDMMiI1 is developed to work with CAD/CAM software and the machining experiments were proceeded on the Sodick A5OR. A theoretical model for cylindrical electrode wear compensation is derived based on the uniform wear method. The compensation is added to the machining program that is produced with CAD/CAM software, real-time compensation is realized during the machining process. The post-process program is developed with VC++ language, it includes the module of wear compensation, machining simulation, serial communication and machining database, which solved the problem encountered during applying the normal CAD/CAM system in the EDMMi11. As a result, there are still many parameters needed to be set according to the experiments, and the post-process program can抰 be directly integrated with the CAD/CAM system. The whole systems need to be further consummated.
