    摘要:

    为研究玻璃纤维复合材料钻削轴向力与分层特征,以电镀金刚石钻头和硬质合金麻花钻为钻削工具,对玻璃纤维复合材料进行正交钻削实验,研究钻头的几何形状、刀具材质以及钻削工艺参数对玻璃纤维复合材料钻削轴向力和钻削质量的影响。结果表明,钻削工艺参数直接影响玻璃纤维复合材料的钻削轴向力和钻削质量,高转速、低进给速度和合适的刀具结构、刀具材质能够降低钻削轴向力并改善加工质量。电镀金刚石钻头的轴向力和出口分层损伤大于硬质合金麻花钻的钻削轴向力和钻削出口分层损伤,电镀金刚石钻头的结构优化可以有效改善钻削质量。

    Abstract:

    In order to study the axial force and delamination characteristics of glass fiber composite materials, electroplated diamond drills and carbide twist drills are used as drilling tools to carry out the orthogonal drilling experiments. The effects of the geometry and materials of drilling tools and drilling process parameters on the drilling axial force and the drilling quality are researched. It is concluded that the drilling process parameters have a direct impact on the drilling axial force and the drilling quality. High speed, low feed and suitable geometry, material of drilling tools can reduce the drilling axial force and improve the drilling quality. The axial force and exit delamination damage of electroplated diamond drills are greater than those of carbide twist drill. The optimization of the geometry of electroplated diamond drills is an effective way to improve the drilling quality.
