“…It is obvious, that material is mainly isotropic (comparing of the strength in the transversal and longitudinal direction). It is not necessary to consider this anisotropy in the simulation [5,6]. 1.…”

The paper deals with the software DEFORM, which is used for forming simulations at the Regional Technological Institute in University of West Bohemia in Pilsen, and with the issue of acquisition and validation of material data. Material library is an essential part of a software, but sometimes it is necessary to add individual material into the library or edit existing materials to improve their description. The article describes the real material tests and individual parameters that should be considered during material description. Further is shown data conversion for virtual simulations in DEFORM software. At the end, the verification of material description is shown. It is done by the comparing of results given by virtual simulation and by the real forming process. The whole procedure of new material description is shown on the brass CuZn30. Material description is deeply described in this paper.

“…The forming process is influenced by several parameters [6]. Besides the tool shape they are precision of tool manufacturing, properties of the processed material [5], technological parameters (temperature, lubrication) [4] and many other input parameters are influencing the forming process. Individual influences can be divided into two categories.…”

This paper deals with forming of the brass cups. Although brass pressing is very widespread, pressing of cups is not described in more detail in the literature. Existing tooling does not achieve the required accuracy of today's production. Development of new and improved tools are now limited to modifications of existing with uncertain results. This article compares several types of forming tools, which are used for forming of the bass cups, and their influence on the product tolerances. For each tool, the response to change of the input parameters such, as the thickness of the input plate, is also considered. The results are compared with real measured products. The individual tool shapes are analyzed by the Deform 3D software.
