This investigation reveals how drawing process parameters influence friction properties in AISI 304 steel sheets, suggesting important insights for manufacturing.
This study investigates the effect of drawing process parameters on friction properties of AISI 304 steel sheet. In sheet metal forming, friction‐related aspects directly influence the process performance and quality of the manufactured products. In this context, the present study aims to investigate the effect of drawing process parameters on the friction properties of AISI 304 austenitic steel sheets under lubricated conditions. For this purpose, strip‐shaped samples with dimensions of 0.8 × 25 × 450 mm are tested in a device developed and adapted to a sheet metal tribosimulator for performing the strip drawing test. The influence of parameters such as the strip‐sliding speed, normal force, and tool roughness on the average value of the coefficient of friction is analyzed. Several characterization techniques are applied to the strip surfaces after the tests, including hardness tests, roughness analysis, scanning electron microscopy, and X‐ray diffraction. The results demonstrate that an increase in the normal force under lubricated conditions reduces the coefficient of friction by 6–21%. The adhesive and abrasive friction mechanisms are predominant under a low force, whereas plastic deformation of the surface asperities dominates at high normal forces.
