Comparison of Sensitivity-Guided and Black-Box Machine Tool Parameter Identification

Dynamic machine tool simulation models can be used for various applications such as process simulations, design optimization, and condition monitoring. However, all these require that the model replicates real system’s behavior accurately possible. Next to carefully building model, parameterization of is, determining parameter values is based upon, most crucial step. This paper describes application both sensitivity-based black-box identification a tool. It further provides comparison between two methods method sequential assembly. shown increase mode shape conformity by more than 25% significantly reduce damping deviations. economical method, offering chance update dynamic within minutes.
