Original abstract

The objective of this work is to compare the performance of uncoated micro-end-mills and their effect on micro-milling of the Ti6Al4V titanium alloy that had been manufactured in the technology of Additive Manufacturing (AM). In this work, two different geometries of square-end micro-mills with two and four cutting flutes have been used. The effective tool geometry at the real micro-machining is rather problematic, because most of the tools are just down-scaled dimensions of standard cutters, so the cutting geometries might not be working well for all dimensions. The Ti6Al4V titanium alloy was made in technology of Direct Metal Laser Sintering (DMLS). Micro-milling tests were done with use of high precision 5-axis KuglerTM micro-milling centre under dry cutting conditions. The performances were evaluated in terms of surface topography, burrs formation, surface integrity and tool wear.

Cílem této práce je porovnat výkony nepovlakovaných celokarbidových fréz a jejich vliv na mikroobrábění titanové slitiny Ti6Al4V, která byla vyrobena v technologii Additive Manufacturing (AM). V této práci byly použity dvě různé geometrie čelních mikrofréz se dvěma a čtyřmi břity. Účinná geometrie nástroje při skutečném mikroobrábění je poměrně problematická, protože většina nástrojů je ve srovnání s normálními frézami jen zmenšená měřítkem, takže geometrie řezání nemusí pracovat správně pro všechny malé rozměry. Titanová slitina Ti6Al4V byla vyrobena technologií přímého tavení laserem (DMLS). Mikro-frézovací testy byly provedeny s použitím vysoce přesného pětiosého mikrofrézovacího centra KuglerTM za suchých řezných podmínek. Výkony byly vyhodnoceny z hlediska povrchové topografie, tvorby trhlin, integrity povrchu a opotřebení nástrojů.
