基于STEP-NC和XML的开放式数控系统研究

摘要

The limitation of traditional NC program interface ISO6983 was analyzed, and the new standard of STEP-NC and the program file formats were introduced. In order to realize the STEP-NC document network transmission, the features of EXPRESS and XML language were introduced respectively, then the transformation technology and the process of the STEP-NC/XML were researched. The framework of the open numerical control system based on the STEP-NC/XML was presented and its work principle and process were introduced.%分析了当前数控系统编程标准IS06983的不足之处,简要说明了STEP-NC新标准以及其程序文件格式.为了实现STEP-NC文件的网络传输,介绍了EXPRESS语言和XML语言各自的特点,研究STEP-NC/XML转化技术及过程.给出了基于STEP-NC/XML的开放式数控系统的体系结构,并介绍其工作原理和过程.
