[0002] Drilling refers to the process of mechanical processing with a drill bit to make round holes in workpieces. The basic principle of drilling is to use the rotary motion and axial thrust of the drill bit to bring the tool into contact with the workpiece and grind the workpiece. Drilling is prone to "deviation". "Deviation" is the situation where the hole diameter is enlarged and the hole is not round due to the bending of the drill bit and the skewness of the axis of the hole.
