Study of milling of low thickness thermoplastic carbon fiber composites in function of tool geometry and cutting conditions

摘要: The application of carbon fiber reinforced thermoplastic matrix composites (CFRTP) is constantly increasing in various industrial sectors due to their mechanical properties and advantages compared thermoset composite. Nevertheless, CFRTP machining generates a current problem the anisotropy these materials, difficulty impregnation reinforcement matrix, its low melting temperature. For this reason, study conventional operations such as milling achieve geometries with good surface quality reduced cosmetic defects line research great interest. In article, comparison five cutting tools different has been made milling. formation visual pull-out have evaluated for each tool combination parameters. sense, 16.42 μm terms Rz minimum average value complete experiment obtained (tool A).
