ABSTRACT
CNC system plays as the brain of Machine tools. Due to customized manufacturing, many special NC functions are required for special machine tools. Open CNC systems for customized manufacturing are urgently needed. But according to the other research results of open CNC system, complex code programming and debugging are still needed. In this study, an all lifetime upgradable open CNC system structure and implementing method are developed and also a case study is given as well. With this structure, the software of NC system is divided into function related design process and function non-related design process. For software, the function related design process can be realized by graphical modelling in order to ease the heavy design and debug burden. For hardware, fieldbus technology is used. Only fieldbus reconfiguration is needed in the secondary development. With this structure and proposed method, the CNC users who are very familiar with the CNC function requirements can easily do maintenance and secondary development at the shop floor level to realize new NC requirements. Also a case study is given based on the proposed structure and design method. The function maintenance and system upgrading of CNC system can be done in all its lifetime.
