摘要： 采用硬质合金麻花钻进行了碳纤维增强树脂基复合材料直径3mm小孔的钻削试验，研究了工艺参数、刀具磨损对切削力和制孔质量的影响规律.首先，通过钻削试验，测得了不同工艺参数下的钻削力，回归分析得到了钻削轴向力和扭矩与转速和进给速度之间的关系式.然后，通过刀具磨损试验，获得了后刀面磨损量随制孔个数的变化曲线;对孔出口毛刺损伤进行测量统计和分析拟合，得到了毛刺面积与钻削扭矩间的关系式.最后，以材料去除率最大为优化目标，以钻削后无分层且毛刺损伤满足要求为约束条件，建立了工艺参数优化模型，获得了最优转速和进给速度.

Abstract: The carbide twist drill was used for drilling experiments of 3 mm diameter small hole in carbon fiber reinforced resin matrix composites. The effects of process parameter and tool wear on the cutting force and the hole quality were studied. Firstly， the drilling force with different process parameters was measured by drilling test. The relationships between the thrust force， torque， rotational speed and feed speed were obtained by regression analysis. Then， the change curve of flank wear with the number of holes drilled was obtained using tool wear experiment. The relationship between burr area and drilling torque was obtained by measuring and fitting the hole exit burrs. Finally， the maximum material removal rate was regarded as the optimization goal， and drilling without delamination and burr damage meeting the requirements were chosen as the constraint conditions. The optimal rotational speed and feed speed were obtained by establishing the optimization model of drilling process parameters.
