Abstract

The paper investigating the cutting force and surface roughness of SKD11 steel considers the effect of heat treatment on the workpiece during milling by high frequency induction thermal assisted. The unchangeable microstructure of SKD11 at room and 200oC was first captured, compared and confirmed. Cutting force and surface roughness after milling SKD11 was then measured at room and 200oC temperatures in the same cutting conditions. Finally, the effect of thermal assisted on the cutting force and surface roughness was analyzed. The results show that the force is greatly reduced and the surface quality of the workpiece is significantly improved under thermal assisted milling. The study also reveals the effectiveness of thermal assisted processing in improving product quality and stabilizing the cutting process
