Experimental Study on Temperature Effect and Tool Wear on Edge Trimming of Carbon Fiber Reinforced Plastics

Abstract

Carbon fiber reinforced plastics (CFRP) are used as structural materials in automotive and aerospace industries because of its superior properties like high strength to weight ratio and high stiffness to weight ratio. Though most CFRP products are produced to near net shape by different composite manufacturing methods, some post machining processes such as drilling, edge trimming are required. In order to shape and smooth the edges of the composite components the edge trimming plays a major role. This research gave the approach of studying the effect of temperature and tool wear on surface roughness obtained during edge trimming of uni directional CFRP with different fiber orientations and quasi isotropic CFRP with the sequence of [90/-45/0/45/90/-45/0/45]S.The effect of coating of tool on tool wear and surface roughness were also studied.
