Implementation of SolidCAM software in an engineering company
Olejníček, Petr ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
This Masters thesis examines the production of a revolver frame and the implementation of a new CAM system for the manufacturing process. This thesis contain four parts. The first part is focused on the current manufacturing process. The second part of the thesis consists of a new proposal to use progressive rotary tools and elements of automation for inspection by the Equator Gauging System. The third part proposes a new manufacturing strategy for the revolver frame. At the end of the thesis, the production times of proposed and current technologies are compared.

Vernet Behringer tools for CNC programming
Mana, Marek ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
The master’s thesis is focused on the possibilities of machining lines of the company Vernet – Behringer. The theoretical part is a brief inclusion of the control system ProNC2 between selected commercially available control systems and are compared ways of programming CNC machine tools. On the machine tool of company Vernet – Behringer are processed mainly thin-walled components, that is why is part of the work focuses on the issue of machining thin-walled parts, the distribution of deflection tools and machined parts. The next part of thesis deals with the design and processing of technical documentation for the machined model part. The practical part deals with the possibilities of the machine and method of programming the control system ProNC2. Programming and practical production on machine were proceeded in company SSI Schäfer s.r.o. The work is focused on practical verification of the production process using simulation and production itself. Finally, it was performed technical - economic evaluation of production.

Analysis of NC programming options for enclosed pockets
Janda, Jiří ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
The aim of this paper is to provide an overview of the available strategies for milling of closed pockets. In particular, it focuses on advanced programming using CAM programs. In the next parts, the work is focused on the analysis of the force load of tools in the machining of the pockets. Here it focuses on the course of forces in milling at the corner of the pocket using different methods of analyzing this load. There are also ways to reduce this burden.

Application of a measuring probes in milling proces on CNC machine MCV1210
Horáček, Kryštof ; Osička, Karel (referee) ; Polzer, Aleš (advisor)
This diploma thesis focuses on the application of measuring probes in the machining process. The main goal of the thesis is to create sample procedures for measuring cycles and functions in a CNC machining process using MCV 1210 and selected measuring software. In the first part of the thesis available methods of machine measurement are outlined with a great emphasis on the description of measurement principles, construction, and measurement signal transmission methods between tool probes and the workpiece. The second part of the thesis deals with the application of measuring probes in the machining of the designed test piece using the Productivity+TM and Sinumerik ShopMill softwares. The work also includes an economic evaluation of the profit of an investment in the mentioned measuring equipment.

Design of injection mold production technology for precision casting
Fendrich, Tomáš ; Polzer, Aleš (referee) ; Zlámal, Tomáš (advisor)
The diploma thesis deals with the design and production of an aluminum injection mold for investment casting. The work briefly describes the technology of investment casting together with a description of the types of molds, their internal arrangement and the most commonly used materials. Another part of the work is devoted to the analysis of aluminum molds machining. Emphasis was placed mainly on those operations, that will be used in production of mold. The practical part describes in detail the process of designing the model and mold, as well as the process of designing production technology. The construction is performed using the program SolidWorks, production technology using the program SolidCam. At the end of the work, the mold is assembled and the functionality of the mold is verified by means of test injection and economic evaluation is made.

Analysis of risks of digitisation of production in an industrial enterprise
Vínovský, Jan ; Polzer, Aleš (referee) ; Rozehnalová, Jana (advisor)
Industry 4.0 is also currently known as the "fourth industrial revolution" or the "digitization of industrial production." Like other industrial revolutions that have already taken place during human development, the latest brings a large number of changes and new methods or technologies that aim to facilitate and make human work as efficient as possible. The final work explains what the "fourth industrial revolution" is, its basic principles and methods that are already used today. Furthermore, this work examines the extent to which Industry 4.0 is introduced in the Czech Republic, the EU and the world, and how it is regulated through legislative frameworks. An analysis was then created focusing on the risks incurred and proposing a solution.

On the milling of refractory ceramic materials
Reiter, Milan ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Diploma thesis is focused on machining of refractory ceramics materials. The theoretical part describes the division of ceramics materials, their structure, manufacture and properties. This part also contains the division of refractory ceramics. In the second chapter, of ceramics materials are described machining. The latest chapter is focused on analyzing the machinability of ceramics materials R - SLI - K. During the experiment, cutting conditions were changed and cutting forces were checked. Then surface roughness was measured and tool wear was observed.
