Tribology testing to friction determination in sheet metal forming processes

Reciprocating sliding tests were performed in order to find the effect of lubricant properties and other variables on the coefficient of friction of the steel sheets “Cold Rolled HSLA 380” in dry and lubricated conditions. For this material, tribology tests were performed with different lubricants. Test results showed that values of the coefficient of friction presented different patterns. The coefficient of friction varies over a wide range with different lubricating conditions and different sliding velocities. For some sliding velocities, the coefficient of friction is stable and lower, while for others it is unstable and higher.
