Abstract
Clamping forces may influence the machining accuracy of the workpiece. The aim of the work is to develop a clamping system which measures during the process the clamping forces applied on the workpiece. Therefore a special chuck jaw has been developed which measures the strain from the clamping process at each chuck jaw. The chuck jaws were designed for the specific application case with a finite element method. With the information out of the process it is possible to find correlations between workpiece deviations and the clamping force. The project was started to correct errors with the aim of better surface quality and smaller variations in tolerances.
