Effects of Machining Surface Defects on Mechanical Parts Performance and Service Life
This article systematically analyzes common machining surface defects including surface roughness, cutting cracks, knife marks, and geometric shape errors. It elaborates how these machining surface defects cause increased friction and wear, reduced contact stiffness, poor sealing performance, and stress concentration, further leading to part fatigue failure, lowered machining accuracy and shortened service life of mechanical components.
