Process Parameters Optimization of Straight Groove Tap Based on AdvantEdge

In order to improve the tapping performance of 316L stainless steel,in this study,the minimum axial force,torque and temperature of all performance indicators were taken as the optimization objectives.In this paper,single-factor test and full-factor test design are combined to optimize the process parameters of the straight groove tap that affect the tapping performance,including spindle speed,tap coating and cutting fluid type.Based on AdvantEdge software for numerical simulation of tapping,entropy weight analysis method was used to determine the optimal combination of process parameters.And comparative experiments were conducted to verify that the tapping effect of the optimized tapping was better.The results show that compared with the original process,the optimized process can reduce the axial force of tapping in processing by 34.452 N,the torque by 1.137 N·m,the temperature by 18.148℃,and the chip tapping capacity is improved.
