传统的刀具在加工钛合金时性能较差。本文采用一种新型刀具材料--无粘结剂立方氮化硼（BCBN）对一种广泛应用的钛合金Ti-6Al-4V进行高速铣削。从切削力、刀具寿命和磨损机理等方面研究了BCBN刀具铣削钛合金时的切削性能和磨损机理。这种类型的刀具在高切削速度下表现出更长的刀具寿命。基于SEM和EDX的观察表明，工件的粘附和磨损是BCBN刀具在高速铣削Ti-6Al-4V时的主要磨损机制。
The performance of conventional tools is poor when used to machine titanium alloys. In this paper, a new tool material, which is binderless cubic boron nitride (BCBN), is used for high-speed milling of a widely used titanium alloy Ti–6Al–4V. The performance and the wear mechanism of the BCBN tool have been investigated when slot milling the titanium alloy in terms of cutting forces, tool life and wear mechanism. This type of tool manifests longer tool life at high cutting speeds. Observations based on the SEM and EDX suggest that adhesion of workpiece and attrition are the main wear mechanisms of the BCBN tool when used in high-speed milling of Ti–6Al–4V.
