The current paper presents a preliminary study on milling of continuous carbon fiber-reinforced epoxy. The chip forms reveal cutting mechanism with fracture rather than with plastic deformation. The fiber orientation affects both burs formation and cutting force. Serious burs can form in the tool-work configuration, with which fibers do not fail successfully, such as by buckling. Cutting in parallel with fiber axis is recommended. Thermal response of the polymer-based material contributes to the obtained surface finish for different cutting conditions. In general, the milled surface quality is comparable to that of metals.
