Here, we focused our attention on the relation between the shape of cutting edge and flow type chip formation of glass. In order to clarify the relation between the two, scratch tests were conducted using a diamond cutting tool, a diamond grain and some diamond indenters of various shapes. As a result, the following conclusions were obtained; 1. The scratch load and the shape of cutting edge were the two most effective factors for generating flow-type glass chips. Furthermore, it was also observed that the corner radius of the cutting tool and surface texture of the cutting edge play an important role in the cutting action. 2. By observing microscopically, the flow-type chips were found to be a serrated chip. 3. Even when flow-type chips are generated, micro-crack damage in some instances may be found under the machined surface.
