Experimental Investigation of Surface Integrity in Turning of 58SiMn High-Strength Steel

Abstract:

In order to investigate the impact of cutting parameters on surface integrity when high-speed turning 58SiMn without cutting fluid, three-factor three-level orthogonal experiments and single factor experiments based on cutting speed and feed rate are employed, and an empirical model is established. The results of analysis of variance (ANOVA) revealed that feed rate is the dominant factor affecting the surface roughness. With the increase of cutting speed and feed rate, residual tensile stress on the surface becomes larger. Along the depth, micro hardness first decreases and then increases.
