A review on ductile mode cutting of brittle materials |

2018. 2. 14.· Brittle materials have been widely employed for industrial appliions due to their excellent mechanical, optical, physical and chemical properties. But obtaining smooth and damage-free surface on brittle materials by traditional machining methods like grinding, lapping and polishing is very costly and extremely time consuming. Ductile mode cutting is a very promising way to achieve high
