CFRP (carbon fiber reinforced plastic) is a composite material having strong anisotropy. The direction of carbon fibers influences tool life, surface integrity, and machining accuracy. In this study, the experiments based on side milling tests are carried out by changing the carbon fiber direction and the coolant (dry/wet/LN_2). The effects of these changing factors on the cutting force, surface integrity, and tool wear are examined. As a result, the machining accuracy is found to be affected by the radial depth of cut and the direction of the carbon fibers. The use of cryogenic machining improves the surface integrity.
