Although much research has been carried out in the field of the milling of GFRP (Glass Fibre Reinforced Polymer) composites, the complexity of the process is such that it is still not mastered in many industrial cases. The current work is aimed at studying the influence of three different geometries of PCD (PolyCrystalline Diamond) and cemented tungsten carbide cutting tools during the up-milling of GFRP composites at fixed cutting conditions ( = 502 m/min and = 420 mm/min). Delamination, cutting forces and tool wear are compared at the fresh and worn states, and the correlation between the lifespan and the cost of the cutting tool is analysed. The main wearing phase of the tools was performed under the conditions of production in the facilities of a company (Sobelcomp, Loncin, Belgium). The results indicate that the PCD tool with the straight edge, inclined peripheral tooth shape produces the smallest total cutting force and less delamination (shortest and lowest number of delaminated fibres) at both fresh and worn states. Moreover, the grinding ability of PCD makes the cutting tool cost per part lower than for cemented carbide. The PCD tool is therefore the best option to mill GFRP parts.
尽管在玻璃纤维增强聚合物（GFRP）复合材料铣削领域已经开展了大量研究，但该工艺的复杂性使得在许多工业案例中仍未得到很好的掌握。当前的工作旨在研究在固定切削条件（切削速度 = 502 m/min，进给速度 = 420 mm/min）下，三种不同几何形状的聚晶金刚石（PCD）和硬质合金刀具在GFRP复合材料顺铣过程中的影响。比较了新刀具和磨损刀具状态下的分层、切削力和刀具磨损情况，并分析了刀具寿命与成本之间的相关性。刀具的主要磨损阶段是在一家公司（比利时隆鑫的索贝尔康普公司）的生产设施条件下进行的。结果表明，具有直刃、倾斜外周齿形状的PCD刀具在新刀具和磨损刀具状态下都产生最小的总切削力和较少的分层（分层纤维最短且数量最少）。此外，PCD的可磨削性使得每个零件的切削刀具成本低于硬质合金刀具。因此，PCD刀具是铣削GFRP零件的最佳选择。
