Abstract
Machining processes are crucial in industrial applications for shaping steel into specific structural products, and represent a significant portion of the product cost. However, the machinability of lightweight steel is poor, and it exhibits the characteristics of difficult-to-machine materials. This study investigated the effect of adding sulfur on the machinability..... More
