Machine Tool Virtual Model

Abstract

Machine tool development for high speed and highly precise cutting demands employment of advanced simulation techniques, which can enable already in the machine tool design phase to model the feed drive dynamic properties and feed drive control. The paper describes the current state of feed drive complex models development in the RCMT. Influence of an appropriate approach to machine frame structure modelling on the feed drive dynamic properties prediction is discussed together with the influence of the ball screw feed drive mechanical structure parameters. Shown are examples of complex models application in the tasks of machine tool development and optimization. Vision of the machine tool virtual models development aims at the possibility to simulate the cutting process with the employment of the Hardware in the Loop systems and cutting process model.
