Information conversion and Platform Design on Networked Manufacturing Faced STEP-NC

This paper studies the implementation method of the STEP-NC networked manufacturing platform and put forwards the conversion between EXPRESS and XML as well as the networked manufacturing method under the combination of STEP-NC and Internet.The conversion between STEP-NC and XML is implemented with Rose class library and DOM interface.Using the Windows Socket programming technology we realize the network transmitting of STEP-NC program which is written by XML.The programming flow of the conversion between STEP-NC and XML is designed and the networked manufacturing platform of STEP-NC program is designed with the help of existing NC machine tool.STEP-NC is a new NC programming interface standard and is an extension of STEP in NC field.STEP-NC combined with the XML Language,implementing product information integration and shared between separate corporations on Web,information can be shared and communion under long-distance,heterogeneity and different construct environment.
