摘　　要：为了解决ISO6983标准的数控(NC)代码共享问题,研究了一种基于可拓理论的数控代码转换系统。系统的信息定制模块根据机床基本性质、程序格式、代码功能复合元模型,完成对应信息的存储;系统的核问题求解模块负责代码功能参数的转换、代码功能的分解和程序格式的转换;系统的源系统代码输入模块通过运动变换矩阵完成机床类型的选择、代码的输入和代码的词法语法分析;系统的中间文件生成模块根据STEP标准的生成中间文件;系统的目标系统代码生成模块对代码进行最优选择和转换。系统的性能取决于三个复合元和核问题解的的完备性。NC Code transforming system is to solve the problems of sharing ISO6983 NC codes. According to the basic-element theory in extension theory, three kinds of multiple elements were def＇med： basic characteristics of machine tools, NC code functions and NC code format. These multiple elements were saved in the system-information module. The solving key-questions module in the system converted function parame- ters of NC codes, decomposed code functions and transformed the code format. The importing-codes module chose types of machine tools by means of motion transformation matrix, imported codes and analyzed the morphology of NC codes. The creating intermediate-files module generated STEP files for converting NC codes. The exporting-codes module achieved optimal choice and transformation of NC codes. The system performance depends on the maturity of three multiple-elements and key-questions＇ solutions.
