Influence of coatings on durability of cutting inserts during longitudinal turning
Balíček, Martin ; Sámelová, Vendula (referee) ; Jaroš, Aleš (advisor)
This thesis deals with the influence of deposited coatings for durability and tool wear during longitudinal turning of steel CSN 41 1600 (E335) and influence of wear and surface quality. The theoretical part is focused on characteristics of turning technology, application, manufacturing and methods of coating cemented carbide and tool wear. The experimental part of the thesis includes the evaluation of the measured values, a description of the material, used tools and machine tool. The values measured in the experiment imply that the most suitable of the tested tool inserts is WNMG 3-1-NF with applied coating TiAlN + TiN. Surface quality decreases with increasing wear of the tool.

Analysis of wear on cutting edges during turning of main steels
Balíček, Martin ; Sedlák, Josef (referee) ; Jaroš, Aleš (advisor)
This diploma thesis deals with the choice of suitable VBD for longitudinal turning barrel steel OCHN3MFA. In the theoretical part, serving as a basis for the experimental part, the technology of turning, tooling and coating methods was analyzed. In the experimental part, ten VBDs were tested, eight of which were of cemented carbide and two of ceramic. The monitored parameters were force load and tool wear VB. From the evaluated load data and tool wear, a suitable VBD for turning barrel steel was selected. The most suitable VBD for turning barrel steel is VBD – G. Tools VBD – I and VBD – J from ceramics are inappropriate tools for turning barrel steel.
