EXPERIMENTAL STUDY OF CHANGING THE THICKNESS OF THE WALL STAIN ON THE INITIAL STAGE OF THE MECHANICAL DRAWING
A number of experiments were performed to evaluate the influence of the drawing parameters on the thickness of the workpiece in a dangerous section. Considered factors such as the initial thickness of the workpiece and the radii of the rounding of the edges of the matrix and punch. We used billets from two materials, which are typical representatives of materials used for drawing - brass Л63 and alloy AMг3М. To assess the influence of factors, regression analysis methods were used. Based on the results of the experiments, regression equations are obtained that allow one to judge the nature and degree of influence of the parameters under consideration.
