ジャーナル フリーUsers of composite materials are faced with difficulties in machining composite materials, because the knowledge and experiences acquired in machining conventional materials 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.抄録全体を表示PDF形式でダウンロード (2458K) -

ジャーナル フリーThis study aims at establishing quantitative methods for determining the viscoelastic properties of plastics using a ball indenting hardness test. In this paper, the theoretical relationships between strain, flow stress of plastics under a rigid ball indenter and time were analyzed. A simple and intelligible time dependent theoretical expressions for total strain and flow stress of plastics under a rigid ball indenter having a constant load were obtained.抄録全体を表示PDF形式でダウンロード (1141K)
