It is very important to estimate the chip curl diameter and/or the chip curl direction for the chip control. In this paper, the side flow of the chip in orthogonal cutting and turning is experimentally observed, and the relation between the value and various chip forms in turning is investigated. Using the value of the side flow in orthogonal cutting, the method to estimate the curl diameter and the curl direction of the chip in conventional cutting is also described. The results obtained are as follows. (1) The data of the chip width and the chip thickness in orthogonal cutting are available to estimate the values of the side flow in conventional cutting. (2) The chip curl diameter and the chip curl direction calculated by the values of the side flow agree well with the experimental results. (3) This analytical method can be applied to estimate the chip forms in conventional cutting for various cutting conditions (depth of cut, feed, etc.) and tool geometries (corner radius, approach angle).
