In grinding operation, the ground parts accuracy showed by the deviation from circularity is caused by the change of rigidity for radial deformation of the part which is due to the grinding force, and hence, it is very difficult to compensate them to improve the accuracy. This paper is concerned with the active shape controlled cylindrical grinding machine. In the present system, the shape of a part is measured in in-process and the spped of part-revolution is controlled by the results of in-process measurement which is stored in the memory of micro computer in order to synchronize with the measurement point and grinding point. The accuracy is due to the part-deformation, and the part-deformation is caused by the grinding force, more over the grinding farce is related to the speed of part-revolution. That is to say, it is possible that the accuracy is improved by the control of the speed of part-revolution.
