In macro forming it is known that the punch velocity has an influence on the deep drawing process. This influence is due to the velocity depending friction behavior between workpiece and tool. In micro range new possibilities in process control open up due to the small dimensions of tools and parts. Highly dynamic forming machines and a specific optimization of punch velocity are interesting for industrial applications, because high specific forming speeds are easily reached and offer small cycle times. Considering the tribological size effect it is assumed, that phenomenon known from macro scale differs from that in micro scale due to the increasing relation of opened to closed lubricant pockets, leading to an increase of the amount of boundary friction. To understand the influence of the drawing speed, the drawing radius and viscosity of lubricants, punch force – punch travel diagrams are created by strip drawing tests with double deflection. The results show on the one hand that decreasing the drawing radius results in higher punch force. The drawing speed affects the viscosity depended punch force. A high viscosity lubricant and a high punch velocity lead to 1.5 times higher punch forces than a low viscosity lubricant. The low viscosity lubricant shows in use with a low punch velocity 1.25 higher punch forces than a high viscosity lubricant. These results indicate a relevant portion of hydrodynamic lubrication also in micro sheet metal forming. Therefor the size effects cannot be explained only by the lubricant pocket model.
