The procedure of automated process reliability evaluation is developed in order to prevent recurrent defects in
parts manufactured by die stamping. The procedure is based on the analysis of such factors as part design, material,
its mechanical and physical properties; equipment parameters, tool performance, etc. The list of reliability
factors may vary according to type of operation as deformation process is different for each group of operations.
The adjustment of stamping process reliability performance prevents any defects emerging during production of
critical parts as early as the work preparation stage.
