A diamond pellets grinding (DPG) is surface-machining method using a DPG plate. The DPG plate has many diamond pellets with regularity. DPG efficiency depends on a grinding distance between the DPG plate and the work-piece. The grinding distance makes a change caused by the layout of many pellets in the DPG plate. Therefore, we have to examine the grinding conditions from the viewpoint of the grinding distance when we design the layout of many diamond pellets in the DPG plate. This study aims to find the optimum conditions in the DPG. This paper presents the calculation method of the grinding distance. Moreover, this paper discusses the results of processing efficiency and accuracy. Especially, a genetic algorithm is used as the optimization method for decreasing the deviation of the grinding distance at the ground work-piece. This optimized results show that the genetic algorithm can design the layout of many diamond pellets in the DPG plate for which the deviation of the grinding distance is remarkably small.
