A Predictive Model for Tolerance Verification of Bent Sheet Metal Parts

This paper presents a complete model including method and result for tolerance verification of bent sheet metal parts. The method uses a mathematical model to take into account aspects influencing the dimensional accuracy of linear and angular dimensions of bent parts. The model was implemented using a set of experimental data to estimate the dimensional accuracy for dimensions of interest of a specific part. Comparing the prediction data with the measured results allowed validation of the model.
