摘　　要：对PCBN刀具车削加工时的切削力及摩擦系数与切削用量的关系进行试验研究,并与YN10硬质合金刀具对比,结果表明:PCBN刀具特别适于高速条件下的干式切削加工,而且为了提高生产率,采用大进给量切削比大切深切削较省力又省功率。The relationship between cutting force, friction factor and cutting consumption of PCBN is studied. It is illustrated that PCBN cutting tool is superior to YN10 carbide cutting tool. PCBN cutting tool is especially suitable for high-speed and dry cutting condition. In order to increase productivity, large feed save more energy and power than large cutting deep.
