<P>PROBLEM TO BE SOLVED: To provide a grinding machine capable of performing grinding at desired grinding accuracy in the shortest possible grinding time in a finishing grinding irrespective of variations in grinding rigidity. <P>SOLUTION: In the course of a continuous grinding method in which workpieces W of the identical shape are subjected to the step of a continuous grinding, the grinding rigidity is measured in the grinding step of an initial grinding cycle S5 which is a grinding cycle for a workpiece to be initially ground. In the following grinding cycle S6 which is a grinding cycle for workpieces to be ground next and thereafter, a rough grinding step is first carried out, and after that, a grinding rigidity measured during the grinding of a workpiece ground before the present workpiece, a normal grinding force measured during the rough grinding step, and a grinding amount in the final grinding step for the present workpiece are made to calculate a retracting amount. After retracting grinding is performed that makes a retracting wheel retracted only by the retracting amount, the final grinding step is practiced so that the grinding rigidity in the final grinding step is measured. <P>COPYRIGHT: (C)2013,JPO&INPIT |
