A method for dressing a grinding wheel or the like to provide surfaces with two different radii thereon mounts a cutting tool on a radius and angle dresser with a first oscillatable shaft which in turn supports a second oscillatable shaft which is oscillatable independently of the first shaft. The axis of the second shaft is shifted relative to the axis of the first shaft to position the cutting edge at a selected elevation relative to the axis of rotation of the first shaft; and it is locked in position while the first shaft is oscillated to generate a first radius surface on the wheel. The first shaft is then locked and the second shaft is oscillated to generate a second radius.
