Abstract
Increasing the efficiency of utilization of expensive high-speed steels is an important problem of modern production. It is solved by VAZ specialists by introducing low-waste technological processes in manufacturing tool preforms. At present, side milling cutters and edging saws are blanked out from square preforms of rolled sheets. Up to 40% of the sheet goes to waste in blanking. Gear cutters and shavers are commonly produced from forged preforms with a considerable (up to 15 mm for each dimension) size allowance for mechanical treatment. It should also be noted that the microstructure of the forgings often contains coarse grains and grains of different sizes. The aim of the present work consists in determining the possibility of using deformation at a subcritical temperature in industrial-scale production of tools (side milling cutters, edging saws, gear cutters, shavers).
