Abstract

Carbon fibre reinforced polymer (CFRP) gave a huge impact on today’s companies such as automotive, shipping and aerospace due to their high quality and light weight. Even though CFRP are manufactured to their closest shape, but they have to undergo a process called secondary machining. In this study, the edge trimming machining of CFRP will be performed by utilizing three types of router tools with different surface geometry. The three router tools are categorized into fine, medium and coarse toothing. Experiment are conducted in varying spindle speed and feed rate but radial depth of cut will be remained constant. The main objective of this study is to investigate the effect of tool geometrical feature of router tools on the surface roughness of trimmed surface for a specific CFRP material such as surface roughness and in addition, cutting force as well as tool wear. Surface roughness measurement of trimmed CFRP was taken using Mitutoyo Surftest Sj-410. The observation of tool wear for those three types router tool was taken under optical microscope Nikon MM-800, as well as the trimmed surfaces of CFRP. The finding provide evidence that fine toothing is the suitable tool for edge trimming of CFRP with respect to overall averaged surface roughness value.
