A method and apparatus for conditioning steel by grinding at a constant metal removal rate by monitoring net power and the normal force between the wheel and the workpiece, and adjusting the normal force to achieve a given, predetermined metal removal rate is based on the relation between power and normal force at constant wheel speed. A semi-automatic method, by operator control of the normal force, and a fully automatic method are disclosed. Provision for correcting the force in response to wheel wear is optional.
