In order to improve the service life and maintenance efficiency of electrical discharge machining (EDM) machine tools, reduce the process difficulty of EDM for difficult-to-machine materials and complex structural parts in the fields of aviation, aerospace and energy, and improve the sharing and convenience of processing technology services, key technology research on cloud service platform construction of EDM machine tools was carried out, including the system architecture design of platform, design and implementation of software and hardware. Based on the platform, the remote EDM process service test of turbine disk, which is the key component of aero-engine, and the cloud-base operation monitoring of EDM machine tools are carried out, and the validity of the platform is verified.
