Stiffness and Strength of Rock Cutting and Drilling Tools – Drag Bit and Roller Disc Cutters

Abstract

Rock cutting with mechanical cutting tools, such as disc cutters and drag picks, offers substantial prospects for excavation industries as it provides a continuous, automated, safe and cost-effective method of rock fragmentation. Over the last few decades, advances in mechanical excavators have focused mainly on developing relationships between the cutting force and the cutting parameters Publications during candidature
