【Abstract】 This paper introduces cutting tools with large-circular face for glass cutting. It has been evidenced that circular cutting edge is a suitable geometry because it can ensure the actual undeformed chip thickness near the tool corner extremely small and, as a result, the cut surface quite perfect while turning with the same cutting process parameters as those in metal cutting. An equation about the minimum undeformed chip thickness, which has a great deal to do with the cut surface, is presented. Such cutting tools always wear on their flanks more quickly than an ordinary one because of the severe friction between the tool and the cut surface. And the tool wear can be reduced greatly by using a cutting fluid with good lubricating property.更多还原
