Purpose: of this paper is to show the benefits of implementation of management of cutting tools in the company which specializes in metal cutting process, after which the production conditions alows new possibilities for improvement of the tool management. Design/methodology/approach: applied in this paper was identification current state and exploitation conditions of cutting tools on lathes and milling machines and organization of the departments and other services, which are directly involved in the cutting tools management system. Findings: of the controlled testings and analyses in every phase of tool management in departments and other services which are directly involved in the tool management system will help to reduce stock and costs. It is possible to identify which operator makes errors and is responsible for inappropriate use of cutting tool. Some disadvantages have been identified and a few suggestions for the improvement in the tool management system have been given. A result of research is easy to apply in company with developed informatic infrastructure and is mostly interesting for CNC workshops. Small companies and specialized low volume productions have to made additional effort to integrate in clusters. Practical implications: are reduction of cutting tool on stock, reduction of employee, quick access to the necessary cutting tools and data, simplicity in tool order and supply. The most important is possibility to monitor and to identify which cutting tools and employees are weakest parts of chain in tool management system. Management activity should be foreseeable in all its segments, which includes both the appropriate choice and use of cutting tools, and monitoring of unwanted phenomena during the cutting process and usage of these data for further purchase of tools. Originality value: in the paper is turnover methodology applied for determination of management efficacy and formation of employees from different departments in virtual tool management system.

Eksploatacja narzędzi do obróbki plastycznej na gorąco ma znaczący wpływ na zużycie narzędzi oraz jakość wyrobu. W celu poprawienia warunków eksploatacji oraz zwiększenia ich trwałości prowadzi się wiele prac badawczych. Rozwój techniki komputerowe/pozwala na stosowanie nowoczesnych metod analizy procesów obróbki plastycznej (MES), które umożliwiają modelowanie rzeczywistych procesów kształtowania przy nieznacznych założeniach upraszczających. W pracy przedstawiono analizę teoretyczną i wyniki parametrów termomechanicznych narzędzi, uzyskane podczas komputerowej symulacji kształtowania łba wkręta szynowego, oraz przeprowadzono krótką ich analizę.

Exploitation of tools for hot working in metal forming has significant influence on durability of them and quality of final product. For increase of exploitation conditions and durability, many research in this scope are worked. In this work theoretical and experimental results of thermomechanical conditions during forming process of screw spikes are presented.
