Abstract：Effects of hot stamping process parameters on the part formability were researched. Hot stamping process parameters mainly included the stamping speed, blank holder force, friction coefficient and blank temperature. Each parameter was divided into three levels, namely low, medium and high. Combined with the test plan design and simulation model, the influence degree of different process parameters on the formability of parts was studied by variance analysis. At the same time, the quantitative analysis method was used to determine the quantitative influence value of process parameters with different levels on the formability of parts. The results showed that the declining order of the process parameters influence on the thinning rate was the friction coefficient, blank temperature, stamping speed and blank holder force. Among them, the quantitative influence value of the friction coefficient was about 97.3%.
