Abstract
A cutting apparatus for finishing a surface of a substrate of a photoreceptor drum of an image forming apparatus estimates a finish state of the surface on real time with the finishing. The cutting apparatus has a detector to detect a cutting force to a cutting tool from the surface in finishing, a memory to store a cutting force pattern to distinguish the finish state of the surface, comparator means to compare the detected cutting force with the stored cutting force pattern and judging means to judge the finish state of the surface along with the progress of the cutting process.
