Abstract
A chatter boundary system includes a measuring module, a comparison module, and a boundary module. The measuring module measures and collects samples of undulations in a manufactured part. The comparison module classifies a sound signal generated by the undulations as either noisy or quiet. The boundary module determines a continuous boundary between the noisy and quiet undulations based on the samples and the sound signal.
