采用类金刚石（DLC）涂层硬质合金立铣刀米尔斯对碳纤维增强塑料（CFRP）进行了无冷却液侧铣试验。选择了四种类型的DLC涂层端米尔斯：UBMS（非平衡磁控溅射）和AIP（电弧离子镀）涂层具有不同的螺旋角，分别。根据加工表面的3D轮廓、产生的起毛、分层和碳纤维的拔出来评价表面完整性。切削力和刀具磨损相对于纤维取向也进行了检查。提出了使用大螺旋角立铣刀进行倾斜铣削的方法，其中立铣刀倾斜，使得合成的切削力平行于工作表面作用。这种独特的方法能够减少刀具磨损，提高CFRP加工表面的表面完整性。(C)2014年CIRP。
Side milling tests of CFRP (Carbon Fiber Reinforced Plastics) without coolant are carried out by DLC (Diamond-Like Carbon)-coated carbide end mills. Four types of DLC-coated end mills are chosen: UBMS (UnBalanced Magnetron Sputtered) and AIP (Arc Ion Plated) coatings having different helix angles, respectively. The surface integrity is evaluated in terms of 3D profiles of the machined surface, generation of fluffing, delamination and pull-out of the carbon fiber. The cutting force and tool wear with respect to the fiber orientation are also examined. The inclination milling with high helix angle end mill is proposed in which the end mill is tilted in such a way that the resultant cutting force acts parallel to the work surface. This unique approach enables to reduce tool wear and to improve surface integrity of machined surface of CFRP. (C) 2014 CIRP.
