Abstract
A method of cutting metal materials and non-metal materials in a non-combustible gas atmosphere, the method including forming a non-combustible gas atmosphere, providing the non-combustible gas atmosphere to at least one of a cutting part of a machine tool and an area adjacent to the cutting part, and machining the metal materials and the non-metal materials using the cutting part, and where the non-combustible gas includes one of nitrogen gas and carbon dioxide gas, and where the non-combustible gas occupies a proportion of at least 90% of the non-combustible gas atmosphere.
Claims29
A method of selectively cutting at least one of metal materials and non-metal materials in a non-combustible gas atmosphere, comprising:
- forming a non-combustible gas atmosphere;
