Ladění kritických rozměrů nástroje pro výrobu nesymetrického výtažku s využitím MKP za účelem dodržení tolerancí předepsaných na výrobním výkresu součásti

摘要

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