PROBLEM TO BE SOLVED: To provide a cylindrical grinding method for performing cylindrical grinding with high machining accuracy by detecting a chipped part and a protruding part during machining a workpiece and machining to correct the chipped part or the protruding part. SOLUTION: In this cylindrical grinding method, the workpiece is supported by a retractable work rest abutting on a ground part of the rotating workpiece, and while being fed at predetermined feed speed, a rotary grinding wheel cuts in the workpiece to grind the workpiece to have a predetermined diameter while measuring the diameter of the ground part by bringing an in-process gage arm into contact with the ground part of the workpiece. When detecting the chipped part or protruding part formed during grinding the workpiece with the rotary grinding wheel, the work rest is retreated from the workpiece, and simultaneously with the retreat of the work rest, the feed speed of the rotary grinding wheel is made slower than the feed speed before detecting the chipped part or protruding part.
