ABSTRACT:
A grinding machine control system has a position detecting device for generating a position signal indicative of the position of a cutting table which is driven at a variable speed by a cutting motor during a grinding process, and a size measuring device for intermittently measuring the workpiece size. A grinding stone table is reciprocally movable relative to the cutting table and carries a grinding stone for grinding the workpiece. A cutting table position signal and a cutting speed signal are intermittently measured under the control of a timing signal which is synchronized with the period of reciprocation of the grinding stone table during the grinding process and are temporarily held as sampling signals. A transient cutting residual amount signal g.sub.0 is obtained by subtracting the workpiece size signal from the sampled cutting table position signal, an error cutting residual amount signal g.sub.3 is obtained by subtracting the standard cutting residual amount signal g.sub.1 from the transient cutting residual amount signal g.sub.0, and a speed correction signal Vg.sub.3 is obtained by dividing the error cutting residual amount g.sub.3 by the sampling time interval "T". The speed correction signal Vg.sub.3 is added to a sampled cutting speed signal V, and a composite signal composed of the speed correction signal Vg.sub.3 and the cutting speed V is applied to control the cutting speed of the cutting motor until the next sampling time.
