Numerical and Experimental Approach for Roll Grinding Process

This paper presents a study of a vibration problem in a roll grinding machine. The rolling contact between a metal roll and the grindstone may cause the pattern formation on the roll surface during the grinding operation. A self-excited vibration excitation or so-called regenerative chatter excitation is present in the process.
