The application of cutting fluid in milling is critical for efficient machining of challenging materials, such as titanium alloys used in aerospace applications. Tool-internal cutting fluid supply under elevated pressure has demonstrated improved tool life, productivity, and process reliability. However, conventional manufacturing of cutting tools with complex internal channel structures and nozzle designs is both costly and limited in geometric complexity. The design flexibility offered by additive manufacturing (AM) processes, such as Laser Powder Bed Fusion (PBF-LB), enables customized,...
