Interaction of manufacturing process and machine tool

Analysing the machine tool and the machining process individually is necessary in order to tackle the challenges that both have to offer. Nevertheless, to fully understand the manufacturing system, e.g. vibrations, deflections or thermal deformations, the interactions between the manufacturing process and the machine tool also have to be analysed. In cutting, grinding and forming there are important effects that can only be explained through these interaction phenomena. This paper presents the current state of research in process-machine interactions for a wide variety of manufacturing processes. it is based on the findings of the CIRP research group "Process Machine Interaction (PMI)" and on the international publications in this field. Cutting with defined and undefined cutting edges as well as sheet and bulk metal forming are the key processes. The emphasis is on understanding, modelling and simulating all modes of interaction. Additional needs of research in process-machine interaction are identified for future projects. (C) 2009 CIRP.
