Abstract—The process of drawing rectangular sections is conveniently designed with the use of analytical
expressions that make it possible to operatively evaluate different manufacturing factors. The application of a
drawing tool with optimum angles makes it possible to cut down power inputs and reduce the failure and
unsoundness of a blank. A design procedure for the drawing stress of the rectangular section is advanced. For-
mulas for calculating the drawing stress and determining the optimum angles of a channel of the drawing tool
are derived. It is shown that the optimum angles depend on the friction coefficient and the reduction ratio.
