abstract

The surface machining of Carbon Fiber Reinforced Plastics (CFRP) materials is a challenging process, given the heterogeneity and anisotropic nature of these composites, which, combined with the abrasiveness of the fibers involved, can produce some surface damage and extensive tool wear. The cutting temperature is one of the most important factors associated with the tool wear rate and machinability of these materials, which are also affected by the mechanical and thermal properties of the work material and the cutting conditions. In this work, the cutting temperature, forces and surface roughness were measured under different cutting conditions during the ball-end milling of unidirectional CFRP. Cutting speeds ranging from 200 to 350 m/min, a feed rate of 0.063 mm/rev, fiber orientation of (the angle between carbon fibers and feed direction) 0, 45, 90 and 135 degrees, and a 0.5 mm depth of cut were used. The results show that the cutting speed and fiber orientation have a significant influence on the cutting temperature and cutting force. The maximum and minimum cutting forces and temperature were achieved for fiber orientations of 90 and 0 degrees, respectively.
