In this paper,a CAD/CMM workpiece modelling system,which is based on IGES-files,is proposed. In this system,the CAD data of workpiece to be measured are extracted and recognized automatically,and the workpiece model is generated as a result of processing,which is the integration of pure 3D geometry form with corresponding in spection items. The principle of workpiece modelling and the system constructure are presented. Furthermore,an experiment is shown to certify the correctness of the modelling way.
