Abstract
The clamping length of holder-tool often changes with the machining conditions and is the main factor affecting the stiffness and damping values of holder-tool interface. To avoid the need for repeating the measurements, the previous studies identify the joint stiffness-damping parameters based on genetic algorithm and calculate the joint parameters per unit area of holder-tool interface for response prediction. This paper proposes a simplified method to identify the joint parameters by simplifying the continuous contact interface to contact points in side of the clamping part. The equivalent joint stiffness-damping parameters are calculated by an inverse calculation method along the whole frequency band, which is more efficient than the genetic algorithm. The responses of holder-tool assembly with different clamping length are predicted based on the assumption of linear relationship between the stiffness-damping values and clamping length. At last, the experiment cases were carried out to verify the effective of the simplified method.
