On the increase of cutting performance of thread cutting taps with coatings
Vondra, Tomáš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The aim of this master's thesis is to deal with main thread production methods and to study the influence of coatings on tap cutting performance. The high-speed steel cutting taps with different PVD coatings (Physical Vapour Deposition) were tested, while the same cutting conditions were set. Cutting torques were measured and analysed, which together with the results of evaluation of tool wear led to conclusion.
