| Abstract: | A 5-axis commercial Electro-discharge Machining(EDM) CNC system based on PMAC is introduced.The proposed CNC system adopts a full-closed loop motion control architecture in which servo drivers receive velocity signals from PMAC.The system achieves several critical techniques in controlling EDM process such as the gap discharge status detection,servo control for electrode’s forward/backward moving,multi-axis simultaneous control,main axis’ high-speed jump motion and various orbiting motions,etc.The system validated its performance by performing a series experiments such as narrow slot processing and shrouded turbine blisk machining on a commercial EDM machine.Besides,the proposed system was further improved according to the commercial EDM CNC criteria. |
