Abstract:To solve the compatibility of NC codes between ISO 10303 and ISO 14649, this paper built an information model-multiple element RG-function, to express the knowledge of G codes in ISO6983 based on the unit theory in extension theory. According to STEP standard, gave the EXPRESS description-model of G-code information model and realized the instantiation from G-code description-model to generate the STEP files. Constructed the system model of translating G codes into STEP files. Introduced the primary modules in the translating system and emphatically discussed the idea of algorithm in the intermediate-file generating module. ......
