In small feed high speed turning, steel chips do not break by chip breaker. New tool rolling device is developed on which tool rolls some angles periodically and using it breaking of chips is successful which is not able to be broken by usual chip breaker. When a tool rolls periodically, true feed and true rake change and also flow direction of chip changes, and so, bending stress of chips goes beyond the breaking stress by bending moment caused by changing of chip flow. This is the reason why chips are broken.In this paper, mechanism of tool rolling device, analysis of periodic rolling motion, experiments, and mechanism of chip breaking are discussed.
