Abstract This paper introduced a new 5-axis computer numerical control (CNC) system for electro-discharge machining (EDM) based on Linux. In the system, a motion controller of programmable multiaxis controller (PMAC) was employed as the subordinate computer, and a PC-based platform running on the Linux operating system was applied as the principal computer. An environment-friendly human-machine operating interface and various software modules used to implement non real-time tasks were developed based on Linux. Some key programs which serve controlling servo motion, main axis’ high-speed jump motion, 5-asix motion and rolling motion were also designed based on PMAC. By being applied to 5axis EDM machine and carrying out the experiments of processing shrouded turbine blisk and narrow slot, the system validated its performance of strong real-time ability, high stability and reliability as well as stable control for main axis’ highspeed jump motion.
