Study on the Influence of Wire Electrical Discharge Machining on Fatigue Properties of Q345B Materials

Abstract

To study the effect of wire electrical discharge machining (WEDM) on the fatigue performance of materials, the mechanical properties of Q345B material used in the grader frame were tested by the single-surface and double-surface of WEDM in this paper. Through the comparison and analysis of the test results, it is found that the yield strength and fatigue strength of the material processed by double-surface machining are 5.2% and 4.2% higher than those processed by single-surface machining, and the tensile strength has no obvious change.
