“…According to Panico et al [8], the machining of FRP composites presents challenges due to the heterogeneity and anisotropic properties of the material, leading to chip formation mechanisms and process force analysis dependent on the cutting angle of the fibers, as evidenced by various experimental studies [9][10][11][12][13]. In addition, the abrasive nature of the fibers causes rapid and severe wear of the tools, resulting in increased cutting forces, delamination defects, burrs, and a decrease in the quality of the machined surface, as demonstrated by Maegawa et al [14] during the milling of unidirectional (UD) carbon fiberreinforced plastic (CFRP) materials.…”

The aim of this paper is to establish a valid procedure for better understanding all of the phenomena associated with the high-speed machining of glass fiber-reinforced plastic (GFRP) composites. Both rectangular and circular specimens were machined at high cutting speeds (up to 50 m/min) in order to understand what occurred for all values of fiber orientation angles during machining operations. An innovative testing methodology was proposed and studied to investigate the phenomenon of burr formation and thus understand how to avoid it during machining operations. To this end, the forces arising during the machining process and the roughness of the resulting surface were carefully studied and correlated with the cutting angle. Additionally, the cutting surface and chip morphology formed during cutting tests were examined using a high-speed camera. Close correlations were found between the variations in the cutting forces’ signals and the trends of the surface roughness and the morphology of the machined surface.
