High-performance carbon fiber-reinforced polyether-ether-ketone (CF/PEEK) has been gradually applied in aerospace and automobile fields due to its high strength-to-weight ratio and impact resistance. However, the requirement of dry machining often causes the cutting temperature to exceed the glass transition temperature, leading to poor surface quality, which becomes a bottleneck for the dry milling of CF/PEEK. Temperature suppression is an important breakthrough to realize the feasibility of high-speed dry (HSD) milling of CF/PEEK, yet heat partitioning and jet heat transfer mechanisms bring great challenges to the analytical modeling of temperature suppression.
Therefore, Chongqing University and Chongqing University of Technology have jointly conducted a…more
