Abstract
The mini deep drawing is a cold forming process applied in order to realize small parts having dimensions smaller than 20 mm. In the case of such process the small thickness of sheet and the small dimensions of parts are the most important factors that influence the process parameters and can affect the accuracy and quality of the produced mini - parts. A proper clearance between the working tools components is also a very important factor that can permit to obtain mini drawn parts in accordance with their theoretical profile. The present paper analyses the results of investigations made by experiment and simulation concerning the influence of tool clearances values on the accuracy of dimensions in the case of mini scale cylindrical drawn cups made from thin sheets. The deviations from the cups theoretical profile (wall inclination, variation of part diameter) that can occur during deep drawing of such sheets were especially analyzed in the paper.
