Sažetak

It is well-known from practice that only some cups whose height is smaller than diameter can be successfully drawn in one step. Many steps require more tools and larger total manufacturing costs. The main objective of this study was to minimize the number of deep-drawing steps.
The paper presents the application of software DDCP developed for designing the multi-step deep-drawing processes in manufacturing of cylindrical cups. The analysis of the computing results obtained by this software shows that the number of drawing steps is decisively affected by relative height of the given part, while the impact of relative radius is smaller. In the paper a diagram for determining the number of deep-drawing steps is given, which is very suitable for engineers in practice.
Also, various very useful approaches for reducing the number of deep-drawing steps are recommended.
