This paper tests, analysis of the use of K24 YW1 cutting tool, the cutting oi the cutting temperature. The greatest impact on the cutting temperature is cutting speed, but with the cutting speed increases the a- mount of the increase in cutting temperature is decreased. This is because in the cutting process, the speed in- crease makes the vice flank wear increased, the depth of cut decreases, reducing the cutting force, cutting tem- perature with the relative reduction. Cutting the impact of cutting temperature, followed by feed rate, cutting depth is minimal impact. Through the experiment of cutting and cutting temperature of empirical formula, formula for the merger of these three available cutting temperature on cutting the overall empirical formula.%通过实验，分析了使用YWl刀具切削K24时，切削用量对切削温度的影响。对切削温度影响最大的是切削速度，但是，随着切削速度的增加切削温度的增加量是下降的。这是因为在切削过程中，速度的增加使得副后刀面磨损加剧，切削深度减小，切削力减小，切削温度也随着相对降低。切削用量对切削温度的影响其次是进给量，影响最小的是切削深度。通过实验所得的切削用量与切削温度的经验公式，将这3个公式合并可得到切削用量对切削温度的总的经验公式。
