In this study, it was aimed to improve the cutting performance of the cutting tool (drill) used in drilling which is of great importance in the industry. The study includes experimental determination of thrust force and torque occurred during drilling, and analysis of the effects of these cutting loads on cutting tool with the Deform-3D program based on finite element method (FEM). For this purpose, various drilling experiments with uncoated and TiAlN/TiN coated solid carbide drills were conducted on full solid and pre-drilled AISI 1050 samples using different cutting parameters (cutting speeds of 60, 75, 90, 108 m/min and feed rates of 0.15, 0.20, 0.25 mm/rev). Kistler 9272 type dynamometer was used to measure the thrust force and torque occurring during the drilling experiments. The stress effects of the experimentally measured thrust force and torque on the drill were analysed. In order to improve the performance of the drill, the drilling operation was simulated and the relationships between cutting parameters and stresses were investigated using the Deform3D program. The results obtained from the study will provide significant contributions to improving the cutting performance of the drill and to the selection of optimum cutting parameters. The stress analysis approach applied in the study can also be applied to other metal cutting operations such as turning and milling, and evaluations can be made regarding the design of cutting tools.

在这项研究中，旨在改善在钻削中使用的切削工具（钻头）的切削性能，这在行业中非常重要。该研究包括实验确定钻孔过程中产生的推力和扭矩，并使用基于有限元方法（FEM）的Deform-3D程序分析这些切削载荷对切削刀具的影响。为此，使用不同的切削参数（切削速度为60、75、90、108 m / min和进给速度）对全固态和预钻孔AISI 1050样品进行了无涂层和TiAlN / TiN涂层硬质合金钻头的各种钻孔实验。 0.15、0.20、0.25毫米/转）。奇石乐9272型测功机用于测量在钻探实验中产生的推力和扭矩。分析了实验测量的推力和扭矩对钻头的应力影响。为了提高钻头的性能，模拟了钻削操作，并使用Deform3D程序研究了切削参数与应力之间的关系。从研究中获得的结果将为改善钻头的切削性能和选择最佳切削参数做出重大贡献。研究中应用的应力分析方法也可以应用于其他金属切削操作，例如车削和铣削，并且可以对切削工具的设计进行评估。模拟了钻孔操作，并使用Deform3D程序研究了切削参数与应力之间的关系。从研究中获得的结果将为改善钻头的切削性能和选择最佳切削参数做出重大贡献。研究中应用的应力分析方法也可以应用于其他金属切削操作，例如车削和铣削，并且可以对切削工具的设计进行评估。模拟了钻孔操作，并使用Deform3D程序研究了切削参数与应力之间的关系。从研究中获得的结果将为改善钻头的切削性能和选择最佳切削参数做出重大贡献。研究中应用的应力分析方法也可以应用于其他金属切削操作，例如车削和铣削，并且可以对切削工具的设计进行评估。
