2. Grinding process generates self-excited vibration and regenerated chatter marks appear on the workpiece surface

3. Increased grinding noise

4. Grinding burns on the workpiece surface

5. Grinding force increases sharply or decreases

6. Reduced grinding accuracy

7. Grinding surface roughness increases
