Yüksek Mukavemetli Çeliklerde Geri Esnemenin Kalınlık Azaltma Yöntemi ile Telafisi

The sheet metal bending process plays an important role in production and springback is unintended consequence of this operation. If the die performed without knowing amount springback, it difficult to produce parts within acceptable tolerance values. behavior part be bent also affects size die. In particular, case a 90° U bend die, manufacturing cost with compensation method high. Therefore, estimate value at design stage. work, estimation deformation avoid was using thickness reduction for high strength metal. According study, can used effectively compensation. measurement accuracy stage reduces possible limits much experimentation. results showed that 0,2 t suitable eliminate U-bending process. It has been found experimental, empirical finite element are close each other.
