Integrated engineering is a subject that many specialists are concerned with. The problem of integrated engineering depends on the way in which CAD and CAPP stages are solved and also on the way in which the information transfer between these phases is ensured. The present paper is focused on the phase of process planning and presents an innovative original CAPP system. The system is strongly related to product design (CAD) where the concept of constructive-technological entity is applied and facilitates CAPP stage. The present paper presents the system structure and working.
