Study on a reconfigurable model of an open CNC kernel

Based on a behavioral model, in this paper a new dynamic modeling method is presented and used to analyze the life cycle of application objects and their interactions in an open-architecture CNC controller model. Since a CNC kernel has a high capability real-time multi-task controller, it is important to develop CNC software based on non-real-time preempt multi-task operating system (Windows NT). A proper method for software high capability real-time control is employed when open on CNC kernel is designed. Further, the paper develops a solution for how to realize reconfigurable structures in CNC systems and seamless connection between function modules and a system.
