Effects of the granite forming minerals on the surface roughness in the milling processes
The area-based average surface roughness of the minerals was measured in the granite. These component minerals were quartz, mica and feldspars. During the study, the focus was set to include the roughness peaks and roughness valleys. If the focus is poor, the surface roughness cannot be evaluated. Precise measurement is also supported by the precise movement of the InfiniteFocus object-slide. The surface roughness of the selected minerals was calculated by the evaluation software of the microscope. During the experiment, area-based roughness was measured instead of line-based roughness to obtain more accurate results.
