| Abstract: | Introduction was made to the rebuilt real-time Linux-embedded CNC system based on ARM9. Hardware structure of the CNC system was composed of PC and microprocessor and its software consisted of interface layer, non-real-time layer and real-time layer. The real-time patch Xenomai and how to use its API were analyzed. Compared with the traditional structure free of operating system, this plan is more flexible and easy to finish complex functions with good interface. For the development of general CNC system, this new plan is worth referring. |
