The present work deals with temperature effects and parametric optimization in the drilling of continuous glass fiber reinforced epoxy composite. Drilling ability was examined operating a drilling system with different drill bits, feed rate, and spindle speed parameters. The investigation was performed by changing the tool and composite interface. Drilling experiments were carried out under the dry condition. Thrust force and drilling temperatures were measured using dynamometer and thermal camera. Peel-up and push-out delamination were evaluated using an image analyzing tool. Results show that the tribo-mechanical behavior of the drilling operation is affected at different levels by tool coating. This behavior is related to the intrinsic friction properties of coating nature. Response surface methodology was used in the evaluation of experiment results. The feed rate of 0.13 mm/rev, spindle speed of 2425 rpm and HSS-TiN drill bit are found as an optimum drilling parameters and drill type.

切削温度和工艺优化对 GFRP 复合材料钻孔的影响

目前的工作涉及连续玻璃纤维增​​强环氧树脂复合材料钻孔中的温度效应和参数优化。使用不同的钻头、进给速率和主轴速度参数操作钻孔系统来检查钻孔能力。调查是通过改变工具和复合界面来进行的。钻孔试验在干燥条件下进行。使用测功机和热像仪测量推力和钻孔温度。使用图像分析工具评估剥离和推出分层。结果表明，钻孔操作的摩擦力学行为受到工具涂层的不同程度的影响。这种行为与涂层性质的固有摩擦特性有关。响应面方法用于评估实验结果。0.13 mm/rev 的进给率、2425 rpm 的主轴转速和 HSS-TiN 钻头被认为是最佳钻孔参数和钻头类型。
