Towards Virtual Engineering in Machine Tool Design

Abstract

an integrated modeling technique for high speed machine tool design is proposed. The model contains a description of the structure, derived from a Finite Element/Model via modal reduction, compliant guideways with static and dynamic friction, and a continuous or discrete time controller. This modeling tool permits designers to evaluate, during the first stages of design, how the mechanical structure and control contribute to the dynamic behavior of the machine, estimating, for example, the dynamic compliance at the tool, the lost motion due to friction and the tracking error during acceleration.
