摘　　要：为改善316L不锈钢材料的攻丝性能,研究以性能指标轴向力、扭矩、温度最低为优化目标,采用单因素试验和全因素试验设计相结合的方法,对影响攻丝性能的直槽丝锥工艺参数(主轴转速、丝锥涂层、切削液种类)进行优化;基于AdvantEdge软件进行攻丝数值模拟,采用熵权分析法确定最佳工艺参数组合,并通过对比试验验证了优化工艺后的丝锥攻丝效果更佳。结果表明:优化工艺较原始工艺而言,攻丝过程中轴向力降低34.452 N、扭矩降低1.137 N·m,温度降低18.148℃,攻丝卷屑能力提高。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.
