Comparison of Cutting Forces and Cutting Temperatures of Two Drills in High Speed Drilling Carbon Fiber Composite

摘要: 采用金刚石涂层钻头和硬质合金麻花钻头对单向T800碳纤维复合材料进行高速钻削试验，对比分析了两种钻头在不同转速和进给速度下钻削时的钻削力与钻削温度，并研究了钻削力对制孔质量的影响。结果表明：高转速、低进给速度能有效提高孔的加工质量;在相同加工参数下，与硬质合金麻花钻头相比，用金刚石涂层钻头钻削时，钻削轴向力减小40%，钻削温度至少降低17%，更适合钻削碳纤维复合材料。

Abstract: T800 carbon fiber reinforced plastic (CFRP) was drilled by diamond coated drill and carbide twist drill at high speed. The drilling axial forces and drilling temperatures produced by the two cutting tools at various rotational speeds and feet rates were studied and compared; and the effects of drilling axial force on the quality of holes were also analyzed. The results show that high rotation speed and low feed rate can improve the processing quality of holes effectively. Compared with carbide twist drill, the diamond coated drill was more suitable for drilling CFRP as its drilling axial force was reduced by 40% and drilling temperatures was at least reduced by 17% under the same processing parameters.
