Tools for turning technology
Bayer, Martin ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This bachelor thesis is focused on current turning tools. The first part of the work is a short history, which summarizes the development of turning technology. The next part is a basic analysis of turning technology. The third part deals with the used turning tools, which are divided according to individual turning applications. The fourth part divides the tool materials that are used for the production of turning tools. The last part deals with Industry 4.0 and the expected vision of turning tools.

Wear analysis of replaceable inserts in parting of structural steels
Drbal, Martin ; Vítek, Jiří (referee) ; Sedlák, Josef (advisor)
This thesis deals with the analysis of wear of replaceable cutting inserts in turning technology. For the experiment three variants of replaceable cutting inserts were used, all from the manufacturer Dormer Pramet s.r.o. These cutting inserts were used for the successive lapping of two different materials. These were bearing steel ČSN 14 109 and stainless steel ČSN 17 349. The thesis contains a theoretical part which is devoted to turning technology and wear theory. The experimental part describes the cutting test procedure, measurements and analysis of the data obtained. At the end of this thesis, additional analyses are performed to reveal the reasons for the variability of some results.

Influence of a size of a cutting edge rounding of the insert during turning
Tichá, Dana ; Sedlák, Josef (referee) ; Dvořák, Jaromír (advisor)
The work is focused on the durability test of replaceable cutting inserts, which are coated with a newly developed coating. In the work are tested two types of replaceable inserts with different shapers, while three different edge roundings are produced for each shaper. The test is performed on three different materials. During testing, the cutting depth doesn’t change, only the feed changes, where tests are performed on each material at two different feeds. A different cutting speed was chosen for each material and feed, which resulted in a durability of the replaceable insert cca 15–20 minutes. The goal of the work is to find out what is the most suitable rounding of the blade on replaceable cutting inserts, when applying a newly developed coating.

Construction of miniature turning tools with insert
Balhar, David ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The main aim of this bachelor thesis is to design a set of miniature turning tools with insert. Elaboration is divided into four chapters. In the first chapter we can find research, which deals with the issue of the construction of turning tools. In the second chapter appears survey produced miniature types and their uses. The most important is the third chapter, because it deals with the main output, and the actual design of selected types of turning tools. The three of turning knives were selected, which are reviewed in the fourth chapter, both technically and economically.

Optimization of production steering shaft
Hlavinka, Martin ; Kalivoda, Milan (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis deals with the creation of the optimal divided chip in the turning technology. The material for production of the steering shaft is steel C35RC suitable for forming and turning from which semi-finished products are produced at horizontally forming presses. They are machined at the production robotized line where the problem with the undivided chip arises. For the specified set of cutting conditions the uses the cutting tools which aren’t very suitable for the given types of technological operations. The recommended values of cutting conditions are different from the specified set of cutting conditions. The result will be choice of new-cutting tools for turning technological operations to shape short divided chip.

Analysis of chip forming mechanism with a high-speed digital camera
Tichý, Vojtěch ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This thesis covers matters related to high-speed digital cameras and their usage in various spheres of human activities, mainly in research of chip forming. Thesis summarises important knowledge needed for creation of high-speed recordings and choice of suitable lenses. Focus is taken on creation of high-speed recordings of chip forming process in turning operation outside grooving by using of different types of chipformers. Main goal is to verify its functionality in specific value range of feed per revolution.

Tool life of ADMX inserts for milling of the S-grade materials
Tejkl, Jakub ; Kouřil, Miroslav (referee) ; Píška, Miroslav (advisor)
This diploma thesis studies the machining of group S materials. In the theoretical part of this thesis these materials were divided into groups and subsequently analyzed. These materials were also analyzed in terms of their impaired machinability. In the practical part of this thesis experimental tests were conducted to determine tool life, tool wear and in the case of testing titanium alloy surface roughness too.
