Abstract
Since the glass-fiber-reinforced plastics (GFRP) is non-homogeneous, the cutting behavior of this material differs from that of a homogeneous material such as steel. It is, therefore, difficult to analogize the tool wear mechanism in GFRP cutting from the data obtained in the cutting of homogeneous materials. In this study, a face turning test was performed on GFRP cylindrical pipes which contained uni-direction fibers (right-hand-winding or left-hand-winding) and others. The cutting resistance and surface roughness were measured to analyze the machinability and the tool wear mechanism in GFRP cutting. Thus, the relation between the fiber orientation and tool wear becomes clear ; e.g., there is a significant difference in the wear rate between right-hand-wound material and left-hand-wound one.
