| The problem of end-face cavity formation in parts produced by cross-wedge rolling was studied in order to reduce materialconsumption. The cavity depth was measured by the displacement method. Twenty-one different cases of rolling wereanalysed by finite element method to determine the effects of process parameters such as the wedge tool angle, thetemperature of material, the tool velocity and the reduction ratio on the depth of end-face cavities. Relationships betweenthese parameters are examined in order to establish dependencies enabling quick and simple selection of a concavityallowance in order to remove the cavities. The equations for calculating the concavity allowance were verified in anexperimental process for manufacturing ball pins with the use of flat tools. Rolling tests were performed using a billet withits length selected in compliance with the established dependencies. The experimental results demonstrate that the pro-posed solution is a viable method for end-face cavity removal. |
