Abstract

The article presents the results of the milling tests - "hard machining" - on the processed (hardened and tempered) material X37CrMoV5-1 (ČSN 19552). At the beginning, the hardness tests of the machined material block were carried out using the Rockwell method. Machining tests were focused on the evaluation of hard machining efficiency and were performed under comparable conditions. At the first stage thin films TiSiN and AlCrN were optimized as a part of a project solution for machining highly and medium hardened materials. Original coating TiAlN was also used for comparison in the second stage. As a result, the flank wear documentation of thin films TiSiN, AlCrN and TiAlN was processed with the same tooling time being set. The flank wear VB and the effectiveness of using the coatings from other perspectives were also evaluated.
