采用K10硬质合金刀具对β钛合金（Ti-3Al-8V-6Cr-4 Mo-4 Zr）进行了车削加工试验。研究了切削温度、切削力、刀具磨损和刀具寿命等性能，并与Ti-6A 1 -4V进行了对比。从刀具几何形状、刀具材料、切削液和走刀轨迹等方面探讨了提高刀具寿命的途径。结果表明：Ti-3Al-8V-6Cr-4 Mo-4 Zr合金的切削温度低于Ti-6Al-4V合金，但切削性能较差。在加工β-钛合金时，由于被加工材料在切削刃上的粘附性很强，硬质合金刀具的刀具寿命约为加工Ti-6Al-4V时的1/2 ~ 1/10。然而，通过设计刀具几何形状和刀具路径，可以大大提高刀具寿命。
The machinability of beta-titanium alloy (Ti-3Al-8V-6Cr-4Mo-4Zr) was evaluated in turning tests with carbide tool K 10. Cutting temperature, cutting force, tool wear and tool life were researched in comparison with those of Ti-6A1-4V. Further, tool geometories, tool material, cutting fluid and tool path were discussed to improve the tool life. The results obtained were as follows ; In spite of lower cutting temperature than that of Ti-6Al-4V, the machinability of Ti-3Al-8V-6Cr-4Mo-4Zr was very poor. In machining of beta-titanium alloy, the tool lives of carbide tools were about 1/2 to 1/10 of those in machining of Ti-6Al-4V because of the very heavy adhesion of the work material on the cutting edge. However, it was possible to improve the tool life considerably by devising the tool geometries and the tool path.
