Abstract (English):
Current requirements to blanks manufactured by metal forming are presented. There are shown data on accuracy and surface roughness of rolled blanks. Different fracture criteria used for the analysis of press forming are analyzed. It is shown that metal tests on Eriksen should not be used for the estimate of the limiting drawing ratio.

Keywords:
mechanical engineering, metal processing, blank quality
