Abstract

The usage of Carbon Fibre Reinforced Plastics (CFRP) has been widely used in aerospace industry over the year for their high strength and lightweight. Service life of a component is highly dependent on the quality of machining. An experimental investigation of the effect of machining parameters in edge trimming of CFRP material is conducted. Machining operation used is edge trimming. The aim of this experiment is to determine the optimized machining parameters namely spindle speed and feed rate in reducing damages during edge trimming specific CFRP material. The second objective of this study is to observe tool wear phenomenon on routers type tool in edge trimming of specific CFRP material. DoE method was used in this research. Taguchi L9 orthogonal arrays were used. Edge trimming of CFRP is conducted using 3- axis CNC Gantry Router Haas GR-510. Surface roughness measurement is taken using Mitutoyo Surftest SJ-410. Cutting force value is recorded using Kistler Dynamometer. Tool wear is observed using measuring microscope MM-800. All this gathered data analysed using ANOVA method. Using the best and optimum machining parameters help to minimize the damages of CFRP in edge trimming. The results from this research reveal that the optimum machining parameter is using low spindle speed (2526 RPM) and moderate feed rate (379mm/min). This research is also proven that feed rate and spindle speed does affect surface roughness and cutting force.
