Primary Institution: Cracow University of Technology
Hypothesis
The study aims to analyze the nonlinear relationships between cutting parameters, cutting forces, and deformations of the aircraft engine body during the drilling process.
Conclusion
The research demonstrates that the combination of Response Surface Methodology and Finite Element Method can effectively model and predict deformations in aircraft engine bodies during drilling.
Supporting Evidence
- The study found that increasing the feed rate adversely affects the axial force and torque during drilling.
- High values of axial force were recorded, exceeding 2200 N, while torque values were relatively low.
- Strong positive correlations were found between cutting parameters and body deflections.
Takeaway
This study looks at how drilling holes in airplane parts can change their shape, and it finds ways to make the drilling process better.
Methodology
The study used experimental tests and mathematical modeling through Response Surface Methodology and Finite Element Method to analyze the effects of cutting parameters on deformations.
Limitations
The study does not account for the verification of calculations made using the finite element method with a real engine body model.
