The usage area of natural fiber reinforced composite materials has been increasing day by day, due to their attaining to not only ecological benefits but also high mechanical properties with their low weight. After the fabrication of natural fiber reinforced composites, they need to be subjected to secondary processes such as milling, drilling and turning processes according to their field of use. In this study, it was aimed to determine milling performance of JFRP and FFRP composites, which are obtained from natural fibers. Experiments were carried out at the different processing parameters. The effects of these parameters on cutting force, vibration amplitude, delamination factor, and surface roughness were investigated. Vibration amplitude and delamination factor increased, and cutting force and surface roughness decreased with increasing spindle speed. Cutting force, vibration amplitude, delamination factor and surface roughness increased with increasing feed rate. The most appropriate values for cutting force, delamination factor and surface roughness were obtained in experiments where WC end mill was used. However, in vibration amplitude, the lowest values were HSS end mill. Delamination factors and surface roughness in FFRP composites were higher than those of JFRP composites. Cutting forces of FFRP composites were lower than those of JFRP composites.
