Influence of Rotational Speed on Accuracy in Measuring MIRS of Aerospace Aluminum Alloy by Incremental Hole-Milling Method
Highlights
- The deviation of measured machining-induced residual stress can be controlled within 35 MPa when the rotational speed is more than 20,000 rpm;
- Shear stress increases by 63% when the rotational speed is below 10,000 rpm;
- The calculated maximum distortion on one of the diagonals of the samples can reach 89% of the measured maximum distortion of one diagonal when the rotational speed is more than 20,000 rpm.
