PURPOSE:To provide a roll grinding method in an on-line roll grinding apparatus in which a roll measuring time can be eliminated as much as possible and an error between a roll profile after it is ground and a target roll profile can be reduced as much as possible. CONSTITUTION:A grinding amount of a roll is calculated from the target roll profile and a measured roll profile and the grinding of the roll is controlled based on this result. A predictive calculation device to predict the roll form changed by rolling and a predictive calculation parameter identification device to identify parameters used in calculating a roll form with a measured roll profile obtained by the roll profile measuring device are equipped and the roll grinding is carried out to approach the target roll profile with either the measured roll profile or a predictive roll profile.
