Design of rationalization of distribution block production
Kobza, Tomáš ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
This thesis focuses on the proposal of rationalization of the production process of the specified part from the company WT-PRO Czech s.r.o. The introductory part is devoted to the description of the specified part and the analysis of the existing production process, focusing mainly on machining operations. Theoretical part is focused on CAD/CAM systems, machining technologies - milling, drilling and threading, which are essential for the production of the component. It also focuses on tooling materials and chucks. In the practical part, the rationalization of the production process is proposed, which concerns two machining operations. A machining centre is specified for these operations, for which new clamping, new tooling, operating instructions and NC codes have been designed in GibbsCAM. The resulting design is described in the new manufacturing process. Finally, a techno-economic evaluation was carried out.

Proposal for rationalization of production technology of a bronze part
Konůpka, Tomáš ; Kolomý, Štěpán (referee) ; Sliwková, Petra (advisor)
The subject of this diploma thesis is a proposal for rationalization of production technology of part made of bronze material CuSn12. Firstly, the manufactured component and the current state of production, including machine times, are described in detail. In the following part, the manufacturing technologies used are described, including turning, drilling and milling. In the next part, the proposal of the production rationalization and the analysis of the time consumption of each operation is described in detail. The last part of the thesis deals with a technical-economic evaluation, including a comparison of the current and rationalised situation. Finally, the achieved objectives and the contribution of the proposal to practical application are summarized.

Design of bench drill
Štěrba, Jakub ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The aim of the work is a bench drill structural design. The first part describes drilling machine categories, compares some of drill press machines available on the market and lists main flaws of most drilling machines on the market. In the second part the basic concept is selected and the actual design of the individual components of the drill is performed. The third part contains selected strength and kinematic calculations. In the last part, the final model of the machine is presented, and the current production progress is discussed.

Solution drilling technologies and clamping units
Adam, Jan ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This Bachelor's Thesis introduces drilling technology, construction of clamping for specific component and its examination in terms of technology and economics.First part of Bachelor's Thesis deals with technology of drilling and with instruments for drilling such as drills and reamers. Next is survey of particular types of drilling machines. Second part of this Thesis is about rules for construction of clamping units and their disposal. Analysis of componet for which is clamping unit constructed. Following by construction of drilling gauge,comparing of incidental times with using the gauge and without using the gauge and finally calculation of investment return in to clamping unit.

Improvement of manufacturing technology of flange
Dvořák, Jakub ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This diploma thesis focuses on improvement of the existing technology of the flange part in cooperation with the company Znojemské strojírny, s r.o. The theoretical part describes the technologies used in machining of the component. Subsequently, cutting materials and aluminum alloys are dealt with. A detailed analysis of the existing technology is performed in the practical part of the thesis followed by rationalization of the production process, which was carried out with respect to time and financial savings. A new technological procedure is developed after the improvement of the current production process. Finally, a technical-economic evaluation of the design improvement process is carried out.

Stiffness of Industrial Robot Arm
Vogel, Jan ; Jurčišin,, Miroslav (referee) ; Knoflíček, Radek (advisor)
Stiffness analysis of an arm of an industrial robot with linear kinematics during a drilling operation. For solving this problem are used optical scanners. Finding the optimal cutting force for drilling by criterions: minimal deformation of robots arms and, at the same time, the emerging vibration from the cutting process is also minimal.
