Abstract
Milling is inevitable for CFRP components to remove excess material in manufacturing industries. Multi-flute sawtooth milling tool was widely used because of its cutting stability and high machining quality. However, obvious damage was observed on the machined surface of the CFRPs when fiber orientation is larger than 90°. Therefore, it is important to optimize the process parameters regarding the surface quality in case of multi-flute sawtooth milling tool. To this aim, the experiment of slotting of the CFRPs was conducted by the multi-flute sawtooth milling tool in this paper. The pit depth was proposed as the criterion to quantify the quality of the machined surface. The milling forces for different parameters and the relationship between the forces and the machined surface quality were researched. Based on the experimental results, it can be obtained that low cutting speed and high feed rate are the optimal cutting conditions for the good machined surface quality and high material removal rate when the up milling surface is the mating surface of CFRP components.
