Özet
The lubrication reduces to effects of friction forces that it is between die and blank holder in deep drawing process. The affecting factors to friction forces are material, surface quality of die and blank holder, temperature, blank holder force and lubrication properties. In this study, the effects of lubricant type on drawing ratio (DR) and forming force have been investigated experimentally. Graphite spray and composition of graphite spray-Teflon (PTFE) materials were used as lubricant materials. Compared with the use of spray, in case of using graphite and Teflon spray composition as lubrication type, it was observed that friction force was decreased. As a result of this decrease, the forming force decreased. The depending on lubrication type, the DR increased maximum 11.26 % for HC300LA sheet material. Also, The DR increased maximum 11.51 % for HC420LA sheet material.
