Which workpiece defect risks escalating during centerless grinding?

💡 Explanation

Chatter marks can induce increased vibration because of positive feedback within regenerative chatter, a form of self-excited vibration. These marks act to amplify existing inaccuracies, therefore causing further chatter downstream, rather than inducing electrical or thermally driven failures.
