1. Process for the control of the step-by-step feed motion of a grinding wheel which is moved backward and forward relative to a workpiece surface to be machined parallel to the latter, wherein for each backward and forward motion of the grinding wheel a sequence of measured values of at least one mode of operating data of the grinding wheel'"'"'s rotary drive is recorded each time, which values change with the friction torque acting upon the grinding wheel, and a feed motion occurs as soon as all measured values in a sequence remain on that side of a limiting value on which a maximum friction torque assigned to this limiting value is not exceeded.
