Grinding chatter - Origin and suppression

Grinding chatter is one of the most critical errors in grinding operations and one that has a strong impact on the ultimate geometrical workpiece accuracy. In the paper the origin of chatter that is particularly due to regenerative effects during inner and outer diameter as well as surface grinding is explained. After the discussion on its influence on surface quality, the possibilities related to process monitoring for the detection of chatter during grinding are presented. Special attention is paid to the suppression of chatter e.g. by employing active or passive damping methods. Furthermore, information on a suitable procedure to conduct a stability assessment for grinding machines is provided.
