ABSTRACT:
In a numerically controlled grinding machine of the type which is adapted to perform a machining operation on the basis of the feed amounts specified as relative amounts in various modes of different grinding wheel feed speeds, a feed controller comprising in combination: a contact detector adapted to produce a contact signal upon detection of contact of the grinding wheel with a workpiece; a non-grinding feed remainder detector including a counter for counting feed control distribution pulses to detect the remainder of a preset feed amount at least in a non-grinding mode from a variation in the count value of the counter during a period between a time point of starting the non-grinding mode and a time point of receiving the contact signal from the contact detector; and a feed mode changing means adapted to change the feed mode of the grinding wheel in such a manner as to effect the remainder of the non-grinding feed at a speed lower than that of the non-grinding mode in response to the contact signal from the contact detector.
