Forecasting the durability of tools for various technological processes, determining the dominant destructive mechanisms or their impact on the "life time" of the tool is very important. In the paper presents the research on tools wear of different geometric parameters in selected plastic working processes were presented. Numerical calculations of the tool wear in the process of forward extrusion and drawing were carried out using the MSC MARC program, based on the Finite Element Method. In order to determine the amount of wear of dies and drawing dies, the Archard model was applied. The model was implemented in the FEM-based program. As a result of the research, the areas on the surface of tools, which are particularly exposed to significant wear were determined, depending on their geometry.
