摘　　要：非调质易切削钢YF45MnV具有优良的机械物理性能,是经过精密锻造或热轧并控制冷却后即可达到通过调质处理才能获得的良好综合性能的一种高效节能钢材。为研究非调质易切削钢YF45MnV的切削加工性能,通过对YF45MnV易切削钢与调质45钢进行切削加工性对比试验研究,验证了YF45MnV易切削钢比调质45钢具有更优良的切削加工性,并给出合理的切削用量。With excellent mechanical and physical properties, non-tempered free-cutting steel YF45MnV is an efficient energy-saving steel which can get a very good general performance by exact forging or hot-rolling and appropriate refrigeration. In this paper, a eontrastive experimental study for the machinability of free-cutting steel YF45MnV and 45 steel was carried out. The experimental results indicate that the machinability of free-cutting steel YF45MnV is much better than that of 45 steel. The reasonable cutting parameters for turning YF45MnV steel were also recommended.
