Change in Deformation Based on Yield StrengthLabel data on the steel we buy, which may or may not be reliable in the first place, become completely worthless when we modify the Sheet Metal Parts (XINGHUI). Holes change strength along the bending line, whether the holes are produced via thermal cut or by drilling or milling. The same is true if the same piece has bends. In addition, punched holes introduce internal stresses that make it even more difficult to consider crowning as a fixed amount of deformation.
Steel is a living thing. Rolling directions create fibers in the structure, so bending across or along the grain will affect both the required bending force and the springback. Thickness VariationsA recently pickled sheet is harder than an aged or oxidized sheet, even after just a few weeks. Moreover, bending a hot plate is not the same as bending an ice-cold plate. Temperature in the shop has an influence on forming, and may lead to different results.
