Glass is an important engineering material. It is widely used in semiconductor, optical, micro-electronics and many other fields. However, glass is not amenable to machining with conventional approach because of its low fracture toughness. To achieve high quality surface finish on optical components, glass must be machined in ductile mode. Compared to single point cutting processes, end-milling can achieve improved material removal rate in machining fracture free surface on brittle material. This paper presents the results of an experimental investigation into microcutting of glass by end-milling. Side-cutting tests have been performed on soda-lime glass workpiece at multiple feeds and radial depth of cuts to obtain fracture free machined surface. The tests were designed to investigate the effect of feed per edge and radial depth of cut on the cutting mechanism at low cutting speed. Experimental results indicate that feed per edge is the most dominant factor that dictates the occurrence of brittle-ductile transition point in the milling process of glass. It has been proved experimentally that fracture free surface can be machined on glass at high radial depth of cut if the feed per edge is sufficiently small.
