    Abstract

    Tribology plays a significant role in enlarging the process limits and ensuring process stability as well as good quality of the forming parts in deep drawing. This paper focuses on assessing lubricant behavior and its influence on tribological conditions during the forming process. A basic condition for efficient usage of the potentials offered by lubrication is the availability of test methods allowing fast and safe evaluation of products. Two specific test stands for sheet metal processing are presented in this paper. These test stands are based on the strip drawing principle. Using these model tests, the capability of a lubricant can be tested under all relevant conditions and its suitability for certain applications can be determined. The experimental results of several tested lubricants will be shown. Subsequently, the results are verified with deep drawing tests of real forming parts.
