Abstract
In a grinding machine, either the revolutional speed of the workpiece or of the grinding wheel is controlled and further the infeed speed of the wheel to the workpiece is controlled so that the optimum grinding condition, having a suitable ratio of the workpiece surface speed to the grinding wheel surface speed and a suitable ratio of the infeed speed to the workpiece revolutional speed, is obtained. The former ratio is maintained despite the wheel diameter decrease caused by wheel dressings.
