A Study on Bistability Analysis and Chatter Suppression for Roll Grinding Process

As chatter vibration in the roll grinding process is the largest limitation in the surface quality of the machined roll. In this paper, the bistability analysis and chatter suppression are performed for further discussion of patterns of the grinding chatter to reduce the cost of enterprises. A new t...
