Abstract

The increasing demand of high precision machine elements manufactured in mass production results in a target conflict with respect to quality control of the production lots, esp. if metal forming techniques are the production principles. <BR />Due to high process forces, kinematic movements of forming tools and imprinted change of material properties during tool and workpiece interaction, a change of the workpiece position within the manufacturing processes generates quality losses in the resulting geometries. <BR />Today, SPC based post-process or in-situ measurements are the basis for the quality control on such production processes. This paper will give an outlook on in-process monitoring of geometrical features based on the targeted component feature specification to be observed. The borderzone quality prediction combined with the collection of relevant process parameters, integrated into an overall inprocess measurement system approach are further intellectual aspects. Initial results out of an ongoing development initiative will be presented.
