Users of composite materials are faced with difflculties in machining composite materials, because the knowledge and experiences acquired in machinining conventional matenals are not directly applicable to the machinability of composite materials. In this study low frequency vibration cutting has been applied to the two-dimensional machining of GFRP (Glass Fiber Reinforced Plastic). The effects of cutting conditions on the cutting force, burr and machined surface roughness have been examined and compared with those using conventional cutting methods. The experimental results have revealed that low frequency vibration cutting is a highly effective machining method with respect to cutting force, burr and machined surface quality.
Key words: GFRP / Low frequency vibration cutting / Cutting force / Burr / Surface roughness
