    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.
