Demand oriented calibration of 5-axis machine tools

The metrological calibration of 5-axis machines requires a huge effort. The Fraunhofer IPT investigates the reduction of these efforts by developing demand oriented measurement strategies. For this the geometrical axis errors will be modelled mathematically and evaluated systematically in order to identify the relevant errors, which have to be indentified. Furthermore the utilization of available measurement systems for the metrological calibration task will be analyzed. The aim is to design calibration strategies tailored to specific 5-axis machine types. Within this paper the principle approaches of this project will be presented
