Abstract Aramid fiber reinforced polymer is an extremely difficult material to be processed. Due to the anisotropy of the material, it often causes defects such as stratification, burning and burr when it is processed in a general manner. In view of the above problems, the micro-milling and grin-ding experiments were carried out respectively. The cutting mechanism of the two processes was analyzed, and the surface roughness and micro-morphology of the two samples were compared. The results show that the surface roughness after micro-milling increases first and then decreases with the increase of feed rate. The surface roughness of grinding increases with the increase of feed rate, which is much higher than that of micro-milling. It is found that the burr phenomenon in the micro-milling process is obvious, and there is a large amount of white condensation on the surface of grinding process. The formation of condensate can be reduced and surface quality can be improved effectively by introducing an air-cooling process during the processing.

Key words： aramid fiber reinforced polymer micro-milling grinding surface topography cutting mechanism surface roughness
