A surface grinding machine comprises a wheelhead assembly including an abrasive disc having a flat stock removal surface and a means for supporting the wheelhead assembly for movement in an axial direction. A microprocessor controller defines a selected infeed program for the wheelhead assembly having at least an initial infeed distance, and an initial feed rate, and a finish infeed distance at a finish feed rate less than said initial feed rate. The microprocessor controller additionally changing the axial location of said retracted and finish positions in response to attrition of the abrasive disc caused by workpiece grinding and disc dressing.
