Abstract

Demand of Hybrid Fibre Reinforce Polymer (HFRP) in aerospace industry are increasing due to its properties which are high strength, stiffness, and durability, as well as resistance to corrosion, wear, impact, and fire. Service life of a component is highly relied on the quality of machining. An experimental investigation of the effect of cutting tool design in edge trimming of HFRP was conducted. Edge trimming was used as the machining operation. The focus of the experiment was to identify the optimum tool geometry, namely the number of flutes and helix angle, as well as the impact of it towards surface roughness, cutting temperature, and chip formation during trimming of HFRP. The DoE method was utilized in this research. Taguchi L9 orthogonal arrays were used. The trimming operation was conducted using the router Roland MDX-540. Mitutoyo Surftest SJ-310 was utilized to measure the surface roughness of the machined part. Nikon MM-800 was used to observe the chip formation. The ANOVA approach was used to evaluate all of the collected data. In edge trimming, using the best and optimum cutting tool geometry helped to reduce HFRP damage. In the end of this research, the optimum tool geometry design for trimming HFRP was expected to be identified.
