Turning of main steels
Svoboda, Kryštof ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
The main theme of the thesis deals with turning of main steels. The basic quantities, force load during turning and geometry of knife with splinter shape are explained in introduction part. Followed by brief overview of instrumental materials. For main steels there is perform an analysis of mechanical and physical properities, alloying elements and their application. In final part there is selection of several replaceable cutting inserts suitable for main steels.

Technology of manufacturing of carbon fibre composites by hot forming
Přikryl, Pavel ; Slaný, Martin (referee) ; Zouhar, Jan (advisor)
This master’s thesis deals with the composite materials and especially aims on the carbon and glass fiber composites. It points out different composition types and manufacturing methods which reflect in the different mechanical properties, final quality of the manufactured part and also in the manufacturing time. The practical part includes two particular manufacturing methods using prepregs, one cured in an autoclave and one by hot compression moulding.

Implementation of the VERICUT System into the Technological Process of Production
Gerbel, Jakub ; Fiala, Zdeněk (referee) ; Slaný, Martin (advisor)
The topic of this bachelor thesis is implementation of the VERICUT verification system into the manufacturing process in cooperation with company JHV Engineering. Based on the theoretical analysis is performed practical part. The 3D model of the CNC machining center was modeled in system Creo Parametric and its kinematic were compiled in the environment of VERICUT system. After evaluation the results, it turned out that there are some deviations between the simulation and the real process. By creating such an exact virtual copy of the machine, or digital twin, collisions can eliminated and production can be planned more efficiently

HSS end milling cutters with PVD coatings and their use in practice
Vondra, Jiří ; Slaný, Martin (referee) ; Jaroš, Aleš (advisor)
This diploma thesis deals with the durability of PVD coating in front groove milling. In the theoretical part there is the analysis of high-speed steels, a survey of milling and an overview of coating methods. The experimental part is focused on the power ratios during milling with a router cutter and its wear. From the experiment it is possible to conclude that nanocomposite coatings reduce cutting forces, but do not produce the most durable tool under the cutting conditions.

On the production technology of a specific part
Kalina, Adam ; Slaný, Martin (referee) ; Píška, Miroslav (advisor)
This document describes the design of new production technology specific part in an engineering company. The specific part is manufactured on a machining center by milling method. To create model was used SolidWorks software and to create CNC program was used SolidCAM program. There is production process created with new and old technologies. There is a comparison of both technologies in conclusion.

Surface heat treatment after 3D FDM print
Břoušek, Lukáš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The topic of diploma thesis are surface heat treatments after 3D print by method Fused Deposition Modeling. In the introduction is located recherche of the given issue. Further, we describe the construction and process of the 3D printer construction, on which will be printed samples for experiments in the next part of the thesis. The aim is to determine the behavior and changes of surface structures of heat-affected samples from different materials. Furthermore, the suitability of the used methods and the possibility of their use in practice.
