The contribution deals with the optimization of the forming process with the use of FE analysis. The impact of the planar anisotropy and friction coefficient on the drawing process was evaluated in the numerical simulation. Optimization of metal blank size and shape with the use of metal forming simulation was also performed. Studied material was galvanized drawing quality steel which is used for the production of the rain gutter end cap. Effects of planar anisotropy and friction coefficient on the quality of steel stamping were evaluated with the use of FE simulation. The effect of anisotropy was also experimentally tested. The aim of this work was to determine the correct steel blank size and shape and to evaluate the effects of planar anisotropy on the thickness variation and wall wrinkling.
