TOOL WEAR IN CUTTING GLASS-FIBER-REINFORCED PLASTICS - THE RELATION BETWEEN FIBER ORIENTATION AND TOOL WEAR.

Abstract

A face turning test was performed on glass-fiber-reinforced plastic (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. A clear relation between fiber orientation and tool wear was established.
