Domain formingcold working
  • lehtmetalli vormimine suurt deformatsioonienergiat ja -kiirust rakendades; alaliikideks on plahvatuslehtvormimine, elektrohüdrolehtvormimine, elektromagnetlehtvormimine (vt lehtvormimine; vrd impulss-stantsimine)
  • a group of forming processes that applies a high rate of strain to the material being formed through the application of high rates of energy transfer - exposive forming, electrohydraulic forming, electromagnetic forming (see: sheet forming; compare: high-energy-rate forging)
impulsslehtvormimine preferred

Domain forging & die forging
  • kuum- või külmvormstantsimise protsess või operatsioon, milles kõrgsurvegaasi salvestatud energiat kasutatakse pressi liuguri kiirendamiseks erakordselt suure kiiruseni, et deformeerida toorikut (vrd impulsslehtvormimine)
    Good to know
    • Ideaaljuhul saavutatakse stantsise lõplik kuju ühe või kõige rohkem mõne löögiga; peamise deformeerimisjõu tekitab pressi liuguri kiirus, mitte selle mass.
  • a closed-die hot- or cold-forging process in which the stored energy of high-pressure gas is used to accelerate a ram to unusually high velocities in order to effect deformation of the workpiece (compare: high-energy-rate forming)
    Good to know
    • Ideally, the final configuration of the forging is developed in one blow or, at most, a few blows; the velocity of the ram, rather than its mass, generates the major forging force.
