摘要(Abstract)：

基于三维热力耦合的有限元模拟和高速切削试验研究了亚微米陶瓷刀具和普通陶瓷刀具切削H13淬硬钢的过程,建立了高速切削的三维有限元模型、磨损模型及求解条件,进行了高速切削试验并对刀尖的磨损形貌进行分析,分析了亚微米陶瓷刀具和普通陶瓷切削过程中的切削力、切削温度和刀具磨损的演化规律。研究表明:经亚微米陶瓷刀具切削上的最高温度随着切削速度的增加而增加,但是当切削到达稳态时温度不再升高;切削力随切削速度的增大而增大;亚微米陶瓷刀具的磨损形态主要是月牙形;工件在切削后的最高温度远小于熔点温度,因此可保证H13钢表面的光洁度;普通陶瓷刀具和亚微米陶瓷刀具相比磨损形态包括后刀面月牙形洼型磨损和前刀面磨损,并易造成崩刃。
