Background Art

[0002] In aircraft assembly, countersinking of sensor targets is a critical process for ensuring the accuracy and reliability of flight control systems. Traditional countersinking processes rely heavily on manual positioning by the operator, which can lead to issues such as inconsistent positioning references and unstable countersink depth control, which can easily cause deviations between the target mounting surface and the theoretical design. Especially when working on complex curved structures or in confined spaces, the lack of dedicated guide mechanisms often leads to countersinking tool offset and cutting vibration, reducing processing efficiency and potentially causing safety hazards such as target substrate damage and even tool breakage.
