Abstract:

Integration of CAD and CAPP system is always a difficult problem in the research, the reason is that the information expression is not consistent. As the output of the CAD system, STEP standard can provide a unified interface to the CAPP system information extraction. In this paper, based on STEP neutral file part feature information extraction and recognition technology, the output from the CAD geometry STEP neutral file includes geometric characteristics information and manufacturing information, the STEP information was transformed into a format recognized by CAPP system. Based on the above research, the process design system was developed based on the information extraction and storage of parts of STEP system, and the system feasibility was proved.
