Parameter Identification of NC-Axes during Regular Operation of a Machine Tool

Abstract:

Monitoring functions of machine tools are of increasing importance to enhance their productivity. They can also be complemented by several system identification approaches which provide additional information. To utilize these approaches, special requirements, e. g. adequate reactions to variant process excitations during the regular process have to be fulfilled. The paper deals with the identification of velocity loop parameters of numerical controlled (NC) axes on a state of the art machine tool and gives an insight on how to correspond to the given requirements. Mainly, this is done by implementing extending modules, of which the model error estimation is pointed out in particular. Experiments with data for a turning operation show the practicability.
