Residual stress and flatness defects in sheet metal parts

Several production processes (such as mechanical and thermal cutting) cause internal tensions and thereby lead to unflat sheet metal parts. These defects in the material impede subsequent working processes.

Flat and stress-free sheet metal parts improve the stability of subsequent processes in sheet metal forming. Thus, the quality of the final product is improved, whereas the amount of refinishing work and scrap decline significantly.
