Papers by Keyword: Single-Point Fly Cutting

Abstract: Single-point fly cutting and nanoindentation test of quartz glass were performed using three different cutting tools, namely, a V-shaped cutting tool, a Vickers indenter and a spherical indenter, to investigate the elastic and plastic behaviors of quartz glass in ductile-regime machining. It was found that these behaviors depend on tool shape and that the V-shaped cutting tool is most effective for removing quartz glass material followed by the Vickers indenter and spherical indenter.

Abstract: The elastic and/or plastic behaviors of glass quartz, the most popular optical material and a hard and brittle material, were studied experimentally from two points of view; static mode and dynamic mode. The static behaviors were investigated by a nanoindentation test and the dynamic behaviors were investigated by a single-point fly cutting (SPFC) test. In the experiments, copper was selected as a material representing soft and ductile materials. From the experiments it was found that the plastic deformation ratio of glass quartz is smaller than that of copper depending on the SPFC conditions, and the area coefficient of the pile-up has the same tendency for both glass quartz and copper.
