Use of Finite Element Method Simulation to Shorten Measurement Cycle of Sheet-metal Parts with Residual Stresses

Sheet-metal parts produced by pressing, stamping or similar technology; usually have residual stresses, which tend to deform them. If these parts are intended to be assembled with other elements, it is necessary to perform measurements to check if constructive dimensions are within acceptable tolerance limits. Such measurements require at least four stages: positioning, clamping, measurement, unclamping. These stages are time-consuming and require manual work. This process is difficult to be automated, because every product needs its own clamping assembly.
