Title

Detection of the Force Distribution Close to the Effective Site in Forming Machines for a Force Control

Abstract
Ever higher demands are placed on the quality and complexity of formed sheet metal parts, whereby the efficiency of the processes may not be affected. Thus it becomes more difficult to ensure process stability. In order to reduce rejected parts it is necessary to improve forming technologies and processes. Closed loop control of process variables with an influence to the quality of a part is a promising approach. Therefor the reliable metrological acquisition of such a parameter is a basic requirement. Forming force respectively force distribution has an influence on component quality and seems to be a suited value. In this paper, a measurement setup and its implementation in a demonstrator is described. First metrological examinations show occurring effects during eccentric load cases and the derivation of spindle forces via additional load paths in the machine frame. This knowledge will be used for the development of a force control.
