采用响应曲面法建立试验方案和丝锥磨损的二阶模型,完成了深冷温度、保温时间、主轴转速3个因素对W6Mo5Cr4V2(W6)高速钢成品丝锥磨损影响的研究。通过测量切削试验后的丝锥后刀面最大磨损量VB,分析各因素之间的交互作用对丝锥后刀面磨损的影响,确定了各个因素的最佳水平范围。优化后的深冷处理工艺和切削参数有3组,分别为主轴转速为200 r/min时,保温时间和深冷温度取4.68 h、-196℃；保温时间为3 h时,深冷温度和主轴转速取-196℃、180 r/min；深冷温度为-150℃时,保温时间和主轴转速取4.68 h、180 r/min。

Test scheme and second-order model of tap wear was established by use of the response surface methodology ( RSM) , and effects of cryogenic temperature, holding time and spindle speed three factors on wear of W6Mo5Cr4V2 (W6) high speed steel finished taps were studied. Through measuring tap flank maximum wear ( VB) after cryogenic and cutting test, the effects of various factors and the interaction between the factors on flank wear of the tap were analyzed, the best range of tap flank wear was obtained. Cryogenic treatment process and cutting parameters are optimized three groups, respectively:when the spindle speed is 200 r/min,the holding time and cryogenic temperature is valued 4. 68 h,-196 ℃;when the holding time is 3 h, the cryogenic temperature and spindle speed is valued -196 ℃, 180 r/min;when the cryogenic temperature is at-150 ℃, the holding time and spindle speed is valued 4. 68 h, 180 r/min.
