Abstract

© 2018 by Taylor & Francis Group, LLC. In this method, a dynamic model of the machine tool in state space is established based on the results of complex finite element models representing the machine tool system, which reduces the amount of computational efficiency significantly but still provides correct responses for the forcing function input and desired output points. The dynamic response of the machine tool is used to simulate the contour profile of the machined surface, and in order to realize the precise simulation in the whole size of the workpiece, the control system is also considered to generate the cutting trajectory in the whole machining process; the cutting force generated in the manufacturing process introduces the interaction between the machining process and the machine tool structures. Thus, the influence of IMPMT on the machined results is achieved rapidly and precisely.
