| 摘 要： | 研究了Al2O3和Al2O3/ZrO2(Y2O3)复合刀具材料的Weibull分布、磨损形态及其切削耐用度。用一元线性回归方法确定Al2O3/ZrO2(Y2O3)刀具的耐用度参数,分析切削条件对Al2O3/ZrO2(Y2O3)复合刀具材料寿命的影响。结果表明:Al2O3和含2%(摩尔分数)及3%Y2O3的ZrO2/Al2O3(Al2O3/ZrO2(2Y)及Al2O3/ZrO2(3Y))复合刀具材料Weibull模数的m值分别是5.6、10.2和11.7,说明Al2O3/ZrO2(3Y)陶瓷的可靠性最优;Al2O3/ZrO2(3Y)复合刀具切削40CrMoNiA合金钢的磨损形态主要来自磨粒磨损和粘结磨损,耐用度参数vc、f、ap的指数值分别为1.3、1.69和0.66,陶瓷刀具更适合高速切削,最大影响因素是进给量(f),在最佳切削条件下(vc=140 m/min,ap=0.5 mm和f=0.3 mm/r)切削耐用度为3 h。 |

| Abstract: | The Weibull distribution,abrasion performance and cutting lifetime of Al2O3 of Al2O3/ZrO2(Y2O3) composites were investigated.The cutting lifetime of Al2O3/ZrO2(Y2O3) cutting tool was established using single linearity regression.The effects of different cutting conditions on the cutting lifetime of Al2O3/ZrO2(Y2O3) composite cutting tool were completely analyzed.The results show that Weibull modula(m) of Al2O3,Al2O3/ZrO2(2Y) and Al2O3/ ZrO2(3Y) composites are 5.6,10.2 and 11.7 respectively,showing that the Al2O3/ZrO2(3Y) composite has the best reliability.The abrasion mechanism during cutting process of 40CrMoNiA alloy steel by Al2O3/ZrO2(Y2O3) cutting tool results from grain abrasion and adhesion abrasion.The parameters in the endurance model,vc,f and a p are 1.3,1.69 and 0.66,respectively.The cutting tool material investigated at present is suitable for high-speed cutting.The maximal influence factor is the amount of feed(f).Under the optimum cutting conditions,vc=140 m/min,ap=0.5 mm and f=0.3 mm/r,the endurance life of the composite cutting tool is 3 h. |
