[en] Fused Filament Fabrication (FFF) is an additive manufacturing (AM) process bringing many advantages over conventional processes such as allowing to obtain complex geometries and personalized designs at a lower cost. However, this process does not allow to reach tight surface roughness nor dimensional tolerances. To overcome these limits, post-production finishing techniques are required, such as finish milling. Yet, due to their intrinsic properties, thermoplastics tend to melt and form burr during cutting preventing the reach of fine surface quality. Therefore, this paper proves the relevance and necessity of using lubrication and shortening the machining time to reduce burr formation and allow to reach better final surface roughness.
