摘要： A method of controlling a machine tone to improve the accuracy of machining which has the steps of detecting the cutting power of a machine tool, comparing the value of the detecting cutting power with a predetermined value of a in-feed power, and controlling the cutting speed of the tool driven by an electric motor so that the in-feed speed is hastened when the difference of both the values of the detected cutting power and a predetermined cutting power is within a predetermined range and the value of the detected cutting power is larger than that of the predetermined cutting power, while the in-feed speed is lessened when the value of the detected cutting power is smaller than that of the predetermined cutting power so as to compensate the wear of the tool. This method is performed by an automatic grinding machine of a roll grinding machine which has a mechanism for compensating the wear of a grinding wheel, a mechanism for compensating the resilient deformations of a grinding wheel, wheel station and roll for controlling the position of the wheel station, means for rotating an electric motor for in-feeding the grinding wheel to cut in normal or reverse direction so as to increase or decrease the cutting, and means for controlling the rotation of the electric motor so as to be proportional to the amplitude of a signal obtained by the in-feed speed of the grinding wheel for compensating the resilient deformation of the grinding wheel, wheel station and roll.
