Abstract
This study clarifies the cause of waviness which is formed on the surface of superabrasive wheels after dressed or trued by a kelly driven rotary diamond dresser and shows how to dress superabrasive wheels in order to obtain preferable accuracy and sharpness. The findings include : (1) The waviness formed on the surface of superabrasive wheels causes from the cyclic variation of supporting force due to the direction change of kelly driving points. (2) Making either (the dresser radius) / (the kelly drive radius), or dressing force small, preferable dressing accuracy can be obtained. (3) The proposed method can bring such a better result as to keep the after-dressed grinding force sufficiently small.
