文摘
- •
We design the experiments to imitate the stack drilling of aircraft structures.
- •
The stacked holes tend to be non-coaxial at a regular direction in stack drilling.
- •
We theoretically explain the formation of inter-layer gaps and non-coaxiality.
- •
The influencing factors are analyzed to help improve the hole quality.
