Abstract

By analyzing the current development of reconfigurable numerical controllers (RNC) and architecture about numerical controllers, this paper presents a RNC architecture based on an embedded system, and analyzes the hardware and software structure of the RNC system. In the hardware structure, it discusses the multifunctional interfaces of MPC5200, and emphasizes configurable hardware functions. In the software structure, this paper first introduces the architecture of the RNC system, then the three layers of the RNC system: user layer, kernel layer and device layer, which have been designed with the character of modularity, extensibility and configurability. Furthermore, embedded Linux and RTAI also have been selected as compact, open, and real-time operating system for RNC. Finally a case is presented to illustrate how to realize the RNC in the cutting machine
