This research investigated the addition of flexibility into a CBN grinding wheel to suppress regenerative chatter, and illustrates some design features that should be present in such a wheel. Flexibility was added by replacing the hub of an aluminumhub CBN grinding wheel with polypropylene, decreasing the bulk stiffness to approximately 12 percent of its original value. Experiments showed that the modified wheel met the design requirements and suppressed chatter, but exhibited increased forced vibration at two frequencies. When the polypropylene between the flanges was replaced by an aluminum insert, one forced vibration disappeared. There is evidence that such a flexible wheel with a homogeneous rim would outperform a standard aluminum hub wheel.
