Integrated simulation method for interaction between manufacturing process and machine tool (original) (raw)

The interaction between the machining process and the machine tool (IMPMT) plays an important role on high precision components manufacturing. In this paper a novel simplified method is proposed to realize the simulation of IMPMT by combining use the finite element method and state space method. In this method, the machine tool's transfer function is built as a small state space which obtained from the complicated finite element model of the machine tool. Furthermore, the control system of the machine tool is integrated with the transfer function of the machine tool to generate the cutting trajectory. Then, the tool tip response caused by cutting force is used for the machined surface prediction. Finally, a case study is carried out for a fly-cutting machining process, the IMPMT simulation is carried out on fly-cutting and the machining results have verified the effectiveness of this method.
