Abstract

In this paper, a research of the impact of the position regarding the main directions of the plane anisotropy of previously derived ellipse shaped aperture (opening) in starting material on the workability of the drawn cold rolled sheet steel is made. This influence is researched using hydraulic drawing of cold rolled sheet steel with previous derived ellipse shaped openings placed in the directions of plane anisotropy. The research aims to show how the position of the previous derived ellipse holes can influence on improving the processing of the cold rolled sheet steel and that will help to solve technological problems in the production when the method of drawing the cold rolled sheet steel with previous derived holes in the starting material is used.
