CYLINDRICAL GRINDING METHOD AND CYLINDRICAL GRINDING MACHINE
In a cylindrical grinding method, rough grinding is performed until a diameter of a workpiece reaches a rough-grinding setting value, and then, first finish grinding is performed until the diameter of the workpiece reaches a first finish setting value while measuring a shape deviation amount of an outer peripheral surface of the workpiece from a perfect round shape. The rough-grinding setting value in the next-time rough grinding step is changed based on a necessary time of the first finish grinding step to time at which the shape deviation amount reaches a first threshold or smaller in the first finish grinding step, and based on a total required time for the first finish grinding step.
