Vibration is a byproduct of the rotating tools common in milling. But excessive vibration leads to chatter, which causes wear on tools and machines—and worse can result in poor-quality parts and excessive cycle times. Here's an overview of the elements involved in vibration analysis to eliminate chatter.

Vibration forms. Common forms of vibration on grinding machines tend to fall into two categories – force vibration and self-excited vibration. Force vibration includes wheel imbalances, damaged bearings, bad motors, or grinding wheel imbalances. Force vibration can be present even when the grinding wheel is not in contact with the workpiece.
