Machining of components on CNC machines
Osička, Petr ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with the manufactory of the rotor for the electric motor on the CNC lathe. The first part describes the function and design of manufactured constituent part. The next chapter designes and describes production process of machining the shaft and next steps of manufactory are described. They basic production capacity calculations are made. In the next part the NC program is designed, which is used to manufacture the shaft as a model product.

Turning technology solution parts "flange" with coated cutting tools
Maršálek, Radek ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This work deals with the use of coated tools in the production of component "flange" on the CNC lathe. The first section describes the process of the coating of tools and an overview of coating tools for machining from well-known manufacturers around the world. Further, it provides the assessment of technology for manufacture the components, the design of semiproduct, the solution of the technological process with the incorporation of the CNC lathe, the assembly of work instructions with calculation of machinery times, and the processing of the NC program and its subsequent verification by simulation of manufacturing process and technical-economic evaluation of the proposed solution.

Application of the hyperMILL 2021.2 SP3 CAM software for machining
Rais, Tomáš ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This Master‘s thesis is dealing with the design of the NC program in hyperMILL software. A machining program has been already created for this component based on which a new optimized program is created. The work includes technical documentation and documents necessary for the creation of the NC program. Specifically, a model of the part, a simplified drawing and setup sheets generated based on mentioned newly created NC program. In the designed optimized program, refined tools are considered for production, which started to be used in companies due to their price. The thesis contains author’s own conclusions and recommendations for practice in addition to performed optimization in the program designed for machining the selected part. The technical evaluation focuses on possible problems related to the use of re-sharpened tools. The economic evaluation is then dealing with the estimation of savings achieved by the use of re-sharpened tools.

Rationalisation of production technology
Konečný, Petr ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
This thesis deals with the rationalization of production technology of selected component. The first part contains a brief introduction of the company NTS Prometal Machining s.r.o. and brief description of the product. The following section is an analysis of existing manufacturing technology. The practical part is focusing on the proposal of rationalization versions of the production process. After evaluation of all possible options of rationalization there has been developed a new technological process with a respect to time and cost savings. Finally there was carried out economical evaluation and recommendation for further production of this component.

Modern CNC machines and their development
Vašíková, Simona ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis is focused on the beginnings of NC and CNC machines from the perspective of historical years, where are included also general information and construction of the most famous machines from history. Also there is their further development, including control system manufacturers and their brief history. The mention of the production of these machines from the perspective of the Czech Republic is included. Part of the thesis is also the division of the current CNC machines according to the type of machined products and the technology together with a sample of 2 selected CNC machines. There is a division of CNC machined parts and evaluation of the use of CNC machines in production. There are the advantages of CNC machines, their accessories and a simple NC program including a product drawing. In discussion there are current technologies in industry, logistics and construction, as well as the current state and attempts to predict future developments.

Possibilities of archiving NC programs in small versus large companies
Mikulec, Jan ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with archiving of NC programmes in engineering companies. The theoretical part describes how the machine tools and their archiving tools are developed. Then the NC programme is characterised together with its structure and the importance of individual characters, followed by characterisation of currently used archiving tools and description of NC programmes labelling that simplifies the archiving. The last part is dedicated to practical examples of the NC programmes archiving and their comparison. The thesis is supplemented with examples of archiving programmes used in chosen companies.
