Abstract
In high speed machining linear direct drives (LDD) enable high dynamics. However, the jerk excites vibration of the machine tool structure and affects the achievable machine accuracy. Therefore, the jerk is limited by the numeric control. One method to avoid excitation of frame vibrations and to increase the dynamics of the feed drive axis is passive jerk-decoupling (JDC) by the means of a mechanical low-pass filter. Nevertheless, passive JDC comes at the price of an additional resonance due to the added mass-spring-damper system. In order to overcome this disadvantage this paper presents a hybrid concept for active JDC. The extension of the passive JDC offers the potential to damp both, the machine structure vibration and the additional JDC-resonance. This paper describes a full state feedback control strategy for damping the critical eigenmodes based on a multi-body model of the feed drive axis. Simulations show that an active JDC reduces the amplitude of the frame- and JDC resonances.
