Abstract
An experimental investigation of the edge effect during chip formation from measurement by non-contact infrared (IR) thermographic techniques is presented. Results are analyzed for variation of the b t ratio (b is the undeformed chip width and t is the undeformed chip thickness) for the orthogonal turning of steel. The degree of edge effect is seen to be influenced greatly by the b t ratio and the distance from the cutting edge. As expected, the edge effect is less prominent with an increase of the b t ratio, for a b t ratio of 5.2 less than 5% of the edge effect being observed on the chip back within the tool chip contact area. From the viewpoint of cutting temperature, the result indicates that two-dimensional chip formation model is a good approximation. © 1995.
