Optimalization of the machining technology
Mohyla, Petr ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
The subject of this bachelor thesis is the analysis of technological process of manufacturing the component „Těleso Kola“ on the turning lathe SV18RA and on the newly bought CNC DOOSAN PUMA 2600 SY. The company LMR s.r.o. which manufactures the part is introduced in the thesis. There are both machines and technological procedures described in the thesis. The goal of this task is comparison of the technological processes from the machine time point of view and consequently economical evaluation.

Determining the best cutting tool for reaming the piston hole in Bosch Diesel company
Rauscher, Tomáš ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
The main goal of this diploma thesis is to increase cost savings on cutting tools, which are used to ream piston hole inside the housing of CP3 diesel pump made by Bosch Diesel s. r. o. Diploma thesis is divided into a theoretical description of the issue, which is initial knowledge for machining tests, and experimental part, whose task it is to find a suitable reamer for this technological operation. Cost savings will be achieved by selecting suitable tool instead of the serial tool that has been used so far.

Selection of an optimal tool for the selected machining technology
Podstata, Jan ; Jaroš, Aleš (referee) ; Fiala, Zdeněk (advisor)
This thesis compares the properties of four types of replaceable cutting tool inserts from different suppliers during milling. The comparative factors are cutting force, material loss of the insert and the roughness of the resulting surface. The thesis is divided into two parts - a comprehensive overview of the current state of knowledge and an experiment. The first part analyzes the load, the possibility of its measurement, surface treatment of tools, milling cutters and replaceable inserts. The experiment took the form of measuring the load during face milling, measuring the surface roughness of the machined material and measuring the material loss of the inserts on an optical strain gauge. The replaceable cutting tool inserts were compared based on the performed measurements.

Technological design of shaft production
Veselý, Ondřej ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis on Technological design of shaft production deals with machining processes in order to realization of production in the conditions of series production, based on the drawing of the part, when the appropriate material and semi-finished product is gradually determined following technological process. This is assigned to suitable machines and tools, the technical economic evaluation related to the production process is carried out. In conclusion it will be used CAD/CAM technology, the prototype component will be made on CNC machine using Edgecam software.

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

On the increase of cutting performance of thread cutting taps with PVD coatings
Grygárek, David ; Fiala, Zdeněk (referee) ; Píška, Miroslav (advisor)
This diploma thesis deals with HSS cutting taps performance in combination with very hard and tribological PVD coating application and their contribution to increasing of cutting properties. Then is described the mechanisms and forms of cutting tool wear. The goal of the experimental part of the thesis was determine, compare and subsequently evaluate cutting properties of threading tools using taps with different types of PVD coatings. During realization of the experiment, constant cutting conditions have been ensured and the only variable were the different types of coating layers. The result of the experiment was measurement of cutting torques depending on time and rate of wear of cutting tools. Measured value are statistically processed and drawn conclusion.

Production of Components for CNC Machine
Kratochvil, Roman ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with a plan for production of a component manufactured by a multifunction CNC machine. First, different generations of CNC machines are described and their advantages and disadvantages mentioned. In the following part of the thesis the material and functionality of the component are examined. Further, production machines and tools are suggested. NC programming software, which is designed with the use of GibbsCAM software, is imported to the machine. During the manufacturing process, the surface being tooled is thoroughly monitored by a 3D measuring device. The last chapter considers technical and economic aspects of the component production.
