How to choose the best grinding process for 3D printed parts

After a grinding distance of about 8 meters, when the diameter of the grinding wheel is reduced to about 45 microns, the surface finish deteriorates. At the same feed rate, reducing the depth of cut from 0.2 mm to 0.1 mm can significantly reduce the wear of the grinding wheel after grinding 10 meters to less than 10 microns.
