![]() This paper deals with research efforts aimed at developing an innovative and open design platform which allows the integration, in a user friendly framework, of the main procedures cited above with other design tools and facilities. These solutions rapidly allow the basic setup of the kinematics of the feed drives and make possible a dynamic optimized dimensioning of all the main subsystems and structures of the machining center. Several modeling and simulation architectures, based on the lumped mass approach and on finite element method, are now well established and widely exploited worldwide. The virtual design of machining centers is a modern and well-known computer aided technique. ![]() The paper presents both the summary of current and past research, as well as research challenges in order to realise a fully digitised model of the machine tool. The simulation of machining operation and its impact on the dynamics of the machine tool and CNC are elaborated. The interaction between the machine tool, controller and cutting process disturbances are discussed with sample examples. Multi-body dynamic models of the machine, which allow integrated simulation of machine kinematics, structural dynamics and control techniques, are discussed. The interaction between the control of the feed drives, cutting conditions and machine tool structure is presented. The kinematic analysis and optimisation of machine tool elements are discussed with sample examples. The structural analysis of machine tools using Finite Element models and their experimental calibration techniques are presented. This paper presents current state of Virtual Machine Tool Technology and related ongoing research challenges. ![]()
