Development method of drawing technological processes based on sheet metal materials anisotropy

The procedure is presented for inclusion of the anisotropy of sheets to the elaboration of drawing practice. A description is given to the basic stages of a mathematical algorithm which simulates drawing transitions of various workpieces in a die. For an axially symmetric piece to be drawn the contour of a shaped blank can be computer - calculated by the successive approximation method as well as the nesting of the blank out of a strip or a sheet. Owing to a proper allowance of elastic strains in deforming by stages, the drawing design procedure presented involving the anisotropy is more precise than the previous one. The procedure is indicated for drawing axially symmetric, box-like and body workpieces of various shapes.
