| Abstract Scope |
Formability under hot stamping process depends on different input process parameters and tribological conditions. Friction is a crucial process parameter for determining formability of a component at higher temperatures. It was observed from previous studies that, the increase in the temperature coefficient of friction increases, whereas in some cases, it is reported that there is a decrease in friction with increase in temperature. Therefore, in this study effect of temperature on coefficient of friction is analysed using Bending Under Tension test (BUT). To conduct experiment L27 Taguchi array with input parameters of temperatures, sliding distances and velocities were used. It was observed that with increase in temperature, sliding velocity, and sliding distance coefficient of friction increases. ANOVA method was used to analyse the influence of process variables on friction coefficient measurement, and also interaction between each process variable. The analysis reveals that temperature have significantly affected the coefficient of friction. |
