Effect of Machined Surface Integrity on Fatigue Performance of Metal Workpiece: A Review

Abstract Fatigue performance is a serious concern for mechanical components subject to cyclical stresses, particularly where safety is paramount. The fatigue performance of components relies closely on their surface integrity because the fatigue cracks generally initiate from free surfaces. This pap...
