On the increase of cutting performance of thread cutting taps with PVD coatings
Samešová, Zina ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This thesis, in its theoretical part deals with the process of cutting, abrasion-resistant layers properties and their contribution to increasing of cutting properties. The second part of the thesis is experimental. It aims to determine, compare and subsequently evaluate cutting properties of threading tools using matrix taps with different types of PVD coatings. During implementation of the experiment, constant cutting conditions have been ensured and the only variable was the different types of coating layers. Outcome of the experiment is measurement of cutting torques in relation on time and rate of wear of cutting tools.
