The closed-die forging is a quite complicated forming process that is affected by a large number of forming factors (such as dimensions and shape complexity of the forged part, mass and shape of raw material (billet), forging die geometry, material properties etc.). In the forging process/die design the choice of the appropriate die land geometry is a difficult and very important task. In this study, the new equations for determining the die land dimensions have been developed by using the regression analysis. The input-output data set was constructed on the basis of the samples from industry. The validation of derived equations was carried out with a case study. These equations can be used for any kind of an axisymmetrical forged part. Proposed equations offer forging process/die designers the possibility to choose the die land dimensions more precisely. In that way, the reduction of the expensive and time consuming trial-and-error procedure in industrial practice is real and possible. On the other hand, determining the proper (optimal) dimensions of die land leads to a successful forging process. Consequently, less mass of raw material, reduction of forging load/work, less die wear as well as best quality of forging parts should be achieved.

“…Sedighi and Pourbashiri [10,11] were concerned to reduce material waste in closed die forging. They proposed a new method, called variable gutter technique, which resulted in a decrease of about 50% of waste material from one forged part.…”

One of the manufacturing processes that can be permanent improved is plastic deformation of metallic materials, as incorporating reserves on the manufacture of products with reduced material and energy consumptions. This paper presents finite element analysis for a closed die forging process, showing the stresses, strains and temperature into deformed part and stresses in the working tools. The analysis of obtained results for different flash dimensions of the working tools has enabled optimization of the forging process studied. To be able to validate the numerical results obtained, experimental tests were conducted. The compared data series show a good agreement between the numerical and experimental data.
