The Effect of Cutting Speeds on Tool Wear and Surface Roughness when Milling Carbon Fiber Reinforced Polymer

Abstract Carbon fibre reinforced polymeric material (CFRP) is increasingly being used to replace metallic materials, particularly in the automobile and aerospace industries. The mechanical properties of CFRP such as excellent weight strength ratio give beneficial outcome improving performance part made from CFRP. However, machining milling difficult challenging due abrasiveness Therefore, influence cutting speeds on tool wear surface roughness when a dry condition aim this paper. test was carried out using 6 mm WC-Co end mill having 30° helix angle. Milling performed with three different speeds, V c (94, 113 132 m/min) while feed rate, f (1800 mm/min) radial depth cut, e (2 mm) were remained constant. =132 m/min resulted increasing by 15 % 10% compared = 94 m/min. damages matrix smearing, delamination pull observed higher speed.
