Tuning of critical dimensions of tool for production of asymmetric shape stamping with the use of fem in order to keep to the tolerations specified at part production drawing

Abstract

The contribution concerns the tuning of critical dimensions of tool for production of the car bodyshell reinforcement asymmetric shape stamping in order to keep to the dimensions and tolerations specified at part production drawing. Final stamping dimensions are generally found out by simulations of drawing process with the use of CAE software in these days. Softwares using the FEM are especially advantageous at intricate asymmetric shape stampings, where the drawing process simulations reach to satisfactory results in comparison with real process. The simulation of drawing process and the evaluation of its results with the use of AutoForm 4.06 software, evaluation of final dimensions of stamping got by simulation and values comparison with dimensions of real stamping got by drawing is described in the contribution. The way of the tuning of the critical dimensions of tool for production of the intricate shape stamping so that all tolerances specified at part production drawing were kept is described in the end of the contribution.
