Experimental Study on Surface Quality in Milling Carbon Fiber Reinforced Plastics

Abstract:

Basing on the milling experiment of carbon fiber reinforced plastics (CFRP), the machining surface qualities of different edge shape and coated tools are researched contrastively. The results show that: when the CFRP is milled by general right-hand edge milling cutter, due to the small tool rake angle, bad tool sharpness, and carbon fibers of upper and lower surface are both subjected to upswept cutting force, the burrs appear at the upper surface of workpiece. But there is no burr at the lower surface. When the CFRP is milled by interlaced edge or herringbone edge diamond coated milling cutter, which are designed to left-hand and right-hand interlace, the carbon fiber of workpiece’s upper and lower surface are subjected to downward and upswept cutting force respectively. There is no burr at the upper and lower surface of workpiece. Compared with interlaced edge diamond coated milling cutter, herringbone edge diamond coated milling cutter is more suitable for finish machining of CFRP.
