The main technologies include NC codes compiling, collision detection and material removal.
The collision detection between grinding wheel and the guide Material Removal.
The essence is not the material removal, but updates the coordinates of the points on the surface and re-modeling.

The mechanical properties of coal depend on its material composition, coal rank, and water saturation.
Macroscopic type of coal can reflect the material composition of the coal to a certain extent, and different lithotypes have different mechanical properties.
