In sheet metal forming, drawbeads are often used to control uneven material flow which may cause deffets such as wrinkles, fractures, surface distortion and springback. Appropriate setting and adjusting of the drawbead force is one of the most important parameters in sheet forming process control. Therefore in this study, drawbead friction test with circular shape bead was performed at various sheets, lubricants(dry, three kinds of lubricants having different viscosities), bead materials and surface treatments of bead surface. The results obtained by drawbead friction test show that the friction and drawing characteristics of deforming panels were mainly influenced by strength of sheet, viscosity of lubricant and hardness of bead surface.
