摘要：The cold bulk forming is a technology that is commonly used in many industrial enterprises. Even though nowadays high demands are posed on labour productivity, quality and own production costs, the findings from practice suggests that not sufficient attention is paid to the issue of tool manage-ment. Also, the theoretical backgrounds and knowledge in this area are not processed in a sufficiently detailed and comprehensive way. This paper submitted to conference deals with the issue of predic-tion of the wear surface of the forming tools and their subsequent renewal. The research at selected materials was focused on the course of their straining in contact of the blank with the tool in the process of cold bulk forming. The experiments were based on a simple performance of the conven-tional upsetting test. On the basis of analysis of the results was determined the mechanism of tool wear by abrasion and was evaluated its impact on the service life time of the tool and also the possi-bility of influencing the quality of final parts.
