Short tool life and inferior surface quality are usually considered as the major problems in cutting FRP (Fibre Reinforced Plastic). Up to this time, most of the research on cutting of FRP put their emphases mainly on the mechanism of tool wear and improvement of tool life. The purpose of this study is to find out a way with which the quality of machined surface in cutting GFRP (Glass Fibre Reinforced Plastic) can be improved. In this study, three patterns of machined surface and four typical fracture models of glass fibre in cutting GFRP, which depend on fibre angle and cutting conditions, have been investigated. Though to change tool geometry has some effect on improving quality of machined surface, the most effective way to obtain smooth machined surface regardless of fibre angle is to make undeformed chip thickness thinner. This leads to the conclusion that milling is the best way to ensure both surface quality and productivity. The cutting conditions of milling to satisfy this requirement are also indicated.
