Production of rotational parts on a CNC machine
Hort, Zbyněk ; Dvořáček, Jan (referee) ; Kalivoda, Milan (advisor)
The main theme of this thesis is a design of rotary part (shaft) production. The study contains the choice of semi-finished product, technological procedure, manufacturing instructions, design and description of machines and tools. It also includes a production drawing of a shaft and NC program by which a functional sample was produced. The economic evaluation is at the end of the thesis. The thesis meets all requirements needed for shaft production using CNC machines.

Technological design of a manufacturing process modernization
Vaverka, Jiří ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The topic of this thesis is to design the modernization process. The aim of this work the design of new machines for a particular component, which would replace the existing ma-chinery used in company-tion in which the component is produced. Introduction is focused on the description of the company and selected components for which it is evaluated di-mensioning, tolerance, functionality and material. The following describes the current ma-chinery engineering company and then are selected machines in two variants, which would replace the original equipment. With these new machines is a technical documentation and is evaluated modernization and environmental concerns. At the end of the re-evaluated results that modernization is beneficial or not.

Custom-made production upon a vertical CNC machine
Okáč, Petr ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The thesis focuses on the topic of custom metalworking, which is familiar to author due to his experience in the field. The first part describes advantages and disadvantages associated with business of small and middle companies, their role in economy and everyday problems they need to solve. The second part compares the manufacturing of a steel part on CNC machine to manufacturing it using conventional machines and evaluating possibilities for custom manufacturing.

FEM for machining simulation
Vojtek, Aleš ; Madaj, Martin (referee) ; Zouhar, Jan (advisor)
The introduction to turning basics, chip separation process, cutting force generation and description of the finite element method. With this knowledge, a cutting simula-tion of AISI 1045 steel was done for 3 different rake angles, which was simplified by using an orthogonal machining model. The next simulation was cutting of AISI 6150 steel with the use of a 3D model of the grooving insert. The results of these simulations were then compared to the experimental results, and feasibility of finite element method was determined together with future recommendations for acquiring more pre-cise results.

Large Turning Centres
Nábělková, Irena ; Jaroš, Zdeněk (referee) ; Blecha, Petr (advisor)
This bachelor's thesis is dedicated to large turning centres. The first part thesis is the summary of large turning centres, their description and types. Usage possibilities of different large turning centres in cutting operations are mentioned too. In the second part, the calculating proposition of a chosen component of large turning centre is solved. This component is spindle-drive. Calculating proposition contains calculation of cutting force, power, total efficiency, utile work and energy.
