The analysis of the forming process of drop forging of a valve on a three-slide forging press (TSFP) is presented. The forging process by means of TSFP can be realized in two ways, which differ in the sequence of the movement of the forming tools. Theoretical analysis based on the FEM simulation and experimental research were made using lead as the workpiece material. A comparison of selected parameters of the two processes was made, these include: stress state index, work done by tools during forming and distribution of strain in drop forging. Moreover, the geometries of the drop forgings were also compared in characteristic phases for both processes obtained from calculation and experiment. On the basis of these results, both variants were evaluated. The advantages of the forging process of a body valve forging on TSFP, in comparison to the forging method with flash on a hammer press, are also given.
