【摘要】 针对16Cr3NiWMoVNbE齿轮倒角加工中存在刀具易磨损甚至崩刃的问题，建立指型铣刀倒角加工仿真模型，基于响应面法分析刀具几何参数（螺旋角α和前角γ）以及切削三要素对刀具磨损的影响。根据仿真结果制备涂层指型铣刀，并进行切削实验验证。结果表明：在转速S=2 000 r/min、进给速度v_f=1 360 mm/min、切削深度a_p=0.5 mm、螺旋角α=8°、前角γ=4°时刀具磨损量最小，刀具切削寿命显著提高。更多还原

【Abstract】 Aiming at the problem of tool wear and even edge breakage in gear chamfering of 16Cr3NiWMoVNbE, a simulation model of finger milling cutter chamfering is established. Based on the response surface method, the influence of tool geometric parameters(helix angle α, rake angle γ) and cutting parameter on tool wear are analyzed. A coated finger milling cutter is prepared based on simulation results and verified through cutting experiments. The results show that the tool wear is minimized and the cutting life is significantly improved when the speed S is 2 000 r/min, the feed speed v_f is 1 360 mm/min, the cutting depth a_p is 0. 5 mm, the helix angle α is 8°, the rake angle γ is 4°.更多还原
