在碳纤维增强塑料复合材料的钻削加工中，切削力是影响孔加工质量的主要因素。本文提出了一个模型，预测的推力和扭矩产生的钻复合材料使用麻花钻。在模型中，横刃切削区采用接触理论，而切削唇切削区考虑斜角切削，并将切削唇切削区划分为三个不同的变形区。该模型考虑了主轴转速、进给速度、钻头直径、刀尖角、刀尖半径、横刃前角、腹板厚度和纤维取向。由该模型预测的切削力与实验结果令人满意的协议，因此可以得出结论，该模型可用于优化复合材料钻削的切削参数和刀具几何形状。
The cutting force is regarded as the main factor that influences the quality of the hole created in the drilling of carbon-fibre-reinforced plastic composites. This paper proposes a model for the prediction of the thrust force and torque generated in the drilling of composite materials using a twist drill. In the model, contact theory is applied to the chisel edge cutting zone and oblique cutting is considered in the cutting lips cutting zone that is considered to have three distinct deformation regions. The model takes into account the spindle speed, feed rate, drill diameter, point angle, nose radius, rake angle of the chisel edge, web thickness, and fibre orientation. The cutting forces predicted by this model are in satisfactory agreement with experimental results and thus it is concluded that the proposed model can be used to optimize the cutting parameters and tool geometries in the drilling of composites.
