Abstract
When designing the process of rectangular profiles drawing, it is convenient to use analytical expressions to estimate promptly the influence of different technological factors. Using the drawing tool with optimal angles allows us to reduce power consumption, destruction and deficiency of a workpiece.
Formulas are obtained for calculation of drawing force and for determining the optimum angles of the channel of the drawing tool. It is shown that optimum angles depend on friction and extract coefficient.
Keywords
