Экспериментально подтверждено, что при резке предварительно изогнутой полосы проката в ножницах с параллельными ножами возникает сложное напряженное состояние, при этом снижается сила резания и, соответственно, энергоемкость процесса резания по сравнению с резанием прямой полосы.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Theoretical comparative analysis of cutting of straight and precurved strip of rolled metal has shown energy efficiency of the second method.
