| Abstract | 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（，），在最佳切削条件下（vc=140m／min，ap=0．5mm和f=0．3mm／r）切削耐用度为3h。 码：A |
| Other 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 ap 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. |
