The results of studies of energy-power indices (contact face pressure, work of deformation) during upsetting with buckling of relatively high workpieces with upsetting ratio 3.5 to 6.0 are summarized in the paper. The relation between work of deformation at the bulk buckling and edging ratio, and similar shape ratios was established. The results are shown that buckling pass is an energy-efficient way of workpieces shaping for bent forgings or dual-forming of some products and belong to the class of dieless (impression-free) bulk pre-forming process.
