摘　　要：通过系统的切削试验,研究了PCBN刀具硬态切削淬硬GCr15轴承钢时切削用量对切削力的影响规律,结果表明:径向力最大,其次是主切削力和轴向力;硬态切削粗加工时的切削力大致为精加工时的3倍;硬态切削力与切削深度和进给量在一定范围内呈线性上升的关系,而与切削速度呈非线性关系.The effect of cutting parameters on cutting forces during hard turning hardened bearing steel GCrl5 with PCBN tool was studied.Experimental results show that the tangential force was the biggest followed with main cutting force and feed force..The cutting forces increas linearly with increase the cutting depth and feed rate,but show nonlinear relations with cutting speed.

关 键 词：PCBN刀具 硬态切削 轴承钢 切削力
