摘要

In this study, it is aimed to determine the friction coefficient between die surface and blank in flexforming (fluidcell forming) process in which a pressurized rubber diaphragm is used to form the sheet. An aluminum square pan is chosen for the workpiece and it is drawn at various pressures and friction conditions (with lubricant, without lubricant, etc.). Numerical models of the process are established with different friction coefficients and results are then compared with the experiments in order to determine the corresponding coefficients of the friction conditions. The displacement of the flange edge is used for comparison.
