초록

Traditional bound abrasive grinding leaves the machine marks and subsurface damages ranging from 1 to few tens microns ms in height. These are removed typically by subsequent craftmen-based loose abrasive lapping, polishing and figuring. Using the multi-variable regression technique, we established a new automated grinding process control method for the removal of loose abrasive lapping from the traditional fabrication process.
