Abstract

The definition of the form-errors of component in nett-forging required the analysis of error generation by considering both thermal and mechanical factors in the forging. To-date, however, most of the analyses have only referred to a single manufacturing cycle. Since forging productions are largely multi-cycle operations, component form-errors can vary with the manufacturing cycle. Using a developed procedure, the temperature change in the die during multi-cycle forward extrusion operations was computed. The computed temperature distributions in the die were then used for initiating the analysis of component form-errors for given manufacturing cycles. The analysis refers to forward extrusion for both single solid die- and compound die-set-configurations.
