Lubrication is one of the process variables that affect the quality of stamping sheet materials. Using a good lubricant can significantly reduce scrap rate and/or improve quality during stamping. In this study, different types of lubricants were evaluated using Strip Draw Test and Deep Draw Test for stamping galvannealed steel sheets. Preliminary finite element (FE) simulations were carried out in order to determine the BHF for Strip Draw and Deep Draw Tests. FE simulations were carried out after the tests in order to determine the coefficient of friction at tool-work piece interface during deep drawing for different lubrication conditions and BHFs. Flow stress data of materials under biaxial load which are used in FE simulations are obtained by Viscous Pressure Bulge tests. Strip Draw Test was used as a preliminary test to evaluate the relative performance of the lubricants. Lubricants that showed good performance in Strip Draw Test were tested using Deep Draw Test. Dimensions of the formed strips and cups and the maximum applicable BHF to draw parts without fracturing were the criteria used for evaluation of lubricants in Strip Draw Test and Deep Draw Test. In general, synthetic lubricants performed better than petroleum-based lubricants in this study.
