The sideward curl of chip is one of the factors by which the chip geometry can be determined, and plays a very important part in chip control. In finish cutting, especially, it is important to control the sideward curl of chip for improvement of chip breaking because chip is hardly curled upward. In this paper, the relation between sideward curl radius of chip and cutting conditions are investigated experimentally, and the cause of sideward curl formation is also discussed. Main results are as follows : (1) Sideward curl radius decreases most remarkably as the depth of cut decreases. (2) The effect of corner radius of tool on sideward curl of chip is remarkable when depth of cut is small. (3) The causes of sideward curl formation are the side flow of chip to be formed at the free edge of chip and the interference of the chip to be formed at the corner of tool.
