Carbon fiber reinforced plastics have outstanding lightweight material characteristics and tensile strength. It is use has been welcomed in the aerospace industry and elsewhere. However, it is mechanical strength properties are influenced by differences in the distribution state of carbon fiber and adhesion intensity with a binding material. It shows intense anisotropy strength wise according to the mechanical properties and carbon fiber orientation. Therefore, when machining it, the tool life becomes short and the surface finish quality of the material becomes unstable and difficult to cut. This paper presents the effects of cutting properties between the fiber orientation and the tool type. We use three types of materials, using straight type end-mills and constant cutting conditions with a cutting speed 70 m/min, a feed rate 250 mm/min and 3mm depth of cut. Our results showed that the tool helix angle 0 degree gave a better surface finish than the other tools, irrespective of the fiber orientation. The helix angle was greatly affected by the fluffy surface. Thrust force (Fz) was a negligible quantity for a helix angle of 0 degree, and the cutting resistance force is low. The cutting temperature is low when cutting chips are fine.
