Abstract
Direct drives and ball screw drives are the most promising feed drive systems for high speed machining. For optimum performance the drives and the feedback control system must be exploited to their physical limits. Thus, input saturation of the feed drives becomes a very important design parameter. A new design method based on a nonlinear stability analysis has been developed to take this into account. Here it is shown, how this method can be used to improve machine tool design and select suitable systems.
