Method for cutting nonmetal material

A method for cutting a nonmetal, comprising steps of:

• providing a thermal effect along a path direction on the nonmetal, wherein the thermal effect grows along a direction opposite to the path direction;
• and
• providing a first cryogenic effect in a first incident direction along the path direction,
• wherein a crack along the path direction is formed as a result of the thermal and the first cryogenic effect therealong for cutting the nonmetal.

A cutting system for a glass substrate, comprising:

• a tension generating device generating a tension stress on a surface of the glass substrate;
• a first heat source exerting a thermal effect along a path direction on the surface, wherein the thermal effect grows along a direction opposite to the path direction;
• a first cooling source to provide a first cryogenic effect in a first incident direction along the path direction, wherein the first incident direction includes a first incident direction component and meets the path direction at a first angle;
• and
• a second cooling source to provide a second cryogenic effect in a second incident direction along the path direction, wherein the second incident direction includes a second incident direction component and meets the path direction at a second angle, and the first direction component, the second direction component, and the path direction therebetween are coplanar,
• wherein a crack along the path direction on the surface is formed as a result of the tension stress, the thermal effect, and the cryogenic effects therealong for cutting the glass substrate.
