Abstract
This paper presents a new kind of multi-axis electro-discharge machining (EDM) computer numerical control (CNC) system which is based on RT Linux platform. Dual-kernel structure of EDM CNC System is proposed to realize real-time task and timesharing task separately. The whole system consists of Real-time Control Module, Drive Module, CNC User Module and Communications among them. The Realtime Control Module implements Real-time control to the EDM CNC machine. Drive Module implements driving of EDM special hardwares. CNC User Module is user manage procedure. Communications among them implement data and signal transfer. Processing of Turbine Blisk is experimentalized to validate the performance of the system. The process and the result simply that the system is Real-time, stable and reliable.
