Carbon Fiber Reinforced Plastics (CFRP) is an encouraging material for aerospace and automotive industries due to its light weight and high strength. Aerospace parts require precise dimensional tolerance and high machined surface quality for safety and reliability. Routing process is needed to produce satisfactory dimensional accuracy of CFRP parts. Machining defects of routing process are related to the cutting mode with respect to cutting angle and bonding strength between carbon fibers and polymer matrix. When the polymer matrix is transformed from polymer to amorphous state, bonding strength is declined. Therefore, cutting temperature is a critical parameter for CFRP machining process because glass transient temperature is relatively low. In this paper, cutting temperature was measured using thermal imaging camera. Machined surface roughness and maximum fiber pull-out depth were analyzed with respect to feed, spindle speed, and laminate structure.
