Ductile-mode Cutting of Glass using Fly Cutting (1st report)

Effect of tool materials for surface

Abstract

A fly cutting allows the glass to be cut 10 times more in depth than turning in ductile-mode. In this research, soda lime glass work pieces were processed by fly cutting with an ultra-precision lathe and influence of the surface by the tool materials (carbide tool (K10) and binder less cBN) were investigated. As a result, the difference in surface roughness, the changing of surface roughness according to cutting distance, and the crack ratio was observed.
