Determination of the residual life of punches of cold forging

A method for efficient determination of residual stresses in punches for cold forging by the level of residual stresses on the stages of manufacturing and operation. As a method of non-destructive testing is used by x-ray diffraction. Residual stresses are determined that compare with the respective permissible level, thus increasing the reliability and efficiency of the press forging operation.

Keywords: punch, X-ray diffractometry, residual stresses, residual resource.
