In this study, ultrasonic-assisted drilling was performed on different heat-treated (T6, T1) AA6061 to investigate the effects of cutting parameters on forces, surface roughness, and tool wear. TiN-coated and uncoated HSS-G drill bits were used in the experiments. The results obtained in the experiments were evaluated according to the general full factorial design and the effect graphs of different drilling parameters were generated. In addition, ANOVA tables were created to evaluate the results. SEM and OM micrographs were used to investigate the tool wear and chip formation. Finally, a multi-response optimization was performed to optimize drilling parameters for minimum cutting force and surface roughness. According to, optimum drilling parameters were determined as AA6061-T6 for material, uncoated HSS-G for a drill bit, 1520 rpm for spindle speed, and highest ultrasonic vibration frequency at 22.5 kHz. In addition, it was observed that ultrasonic vibration has the effect of reducing built-up edge formation on the drill bit.

在这项研究中，对不同热处理（T6，T1）AA6061进行了超声辅助钻孔，以研究切削参数对力，表面粗糙度和工具磨损的影响。实验中使用了TiN涂层和未涂层​​的HSS-G钻头。根据一般全因子设计对实验中获得的结果进行评估，并生成不同钻孔参数的效果图。此外，还创建了ANOVA表以评估结果。SEM和OM显微照片用于研究刀具磨损和切屑形成。最后，进行了多响应优化，以优化钻削参数以最小化切削力和表面粗糙度。据此，对于材料，最佳钻孔参数确定为AA6061-T6，对于钻头，未确定涂层的HSS-G，主轴转速为1520 rpm，最高超声振动频率为22.5 kHz。另外，观察到超声波振动具有减少钻头上堆积的边缘形成的作用。
