Abstract
The temperature field of machine tool structures change constantly in response to external and internal heat changes, as do the thermal deviations of the TCP. This leads to inaccuracy of machined work pieces. Therefore it is necessary to minimize the occurring thermal errors of machine tools. This paper shows, that for accurate thermal error models based on input-output behaviour, a dynamic modelling approach is necessary to capture the time dependent thermal errors. It is shown, based on a simple thermomechanical FEM model, that the ARX model structure outperforms static as well as other dynamic models. Mehr anzeigen
