Abstract

In this paper, the influence law was analyzed, the effective parameter range was determined. Based on the significance analysis of the orthogonal experiment with three factors and three levels, the order of the influence degree of each parameter on the forming quality of the end is obtained. According to the optimized simulation analysis in the effective scheme, the optimal forming process parameters were determined. The results show that the order of the influence of various factors on the diameter of the roll cut is as follows: roll cutting speed> friction factor> baffle gap; the best combination of process parameters is A2B1C1, the friction factor is 0,5, the roll cutting speed is 1/rad · s-1and the baffle gap is 0,1/mm.
