AbstractIn the present research on milling of carbon fiber reinforced polymer (CFRPs) composites widely used in aviation industry, the effects of different cutting speeds and feed rates on the surface roughness was investigated using tungsten carbidecobalt based (WC-Co) carbide cutting tools. A CFRP composite with 6 mm thickness and 24 layers was used as the work-piece. The tests were performed on a CNC vertical processing center with 100, 200 and 300 m/min cutting speeds, 0.05-0.15 and 0.25 mm/tooth feed rates and 1 mm constant cutting width under dry conditions. Following the tests, the surface roughness of the work-piece was investigated. 5.7 µm surface roughness was obtained with 100 m/min cutting speed and 0.25 mm/tooth feed rate.
