The racionalization of machining of gearboxes
Sádlo, Dominik ; Růžička, Petr (referee) ; Sliwková, Petra (advisor)
Content of the thesis is the proposal of new technology using machining centres, including five controlled axis. Benefit of implementation the new nechnology is investigated at machining example, which is the gear housing of a single stage gearbox, manufactured in the company. In the first part of the thesis, the general properties of gearboxes and their housings are analyzed, as well as the procedure of the current proces of the machining representative. In practical part of the thesis is proposed necessary tool equipment and jig equipment, needed for machining of the part. After that are analyzed and filled in time studies, provided by manufacturers of machining centres. On the bases of these studies, were calculated operating times and operating costs per one piece of the housing. In the part of technical and economical evaluation is calculated the return of initial investment, including costs for byuing new machining cente and cutting tools equipment. Finaly are evaluated the overal benefits of the new technology, given the needs of the company.

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.

Optimisation of machining process for an industrial application and a CNC machining centre
Soukupová, Veronika ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.

Streamlining production technology for specified pinion housing
Sádlo, Dominik ; Ohnišťová, Petra (referee) ; Zemčík, Oskar (advisor)
The aim of the thesis is to propose a new technology for the production of the specified pinion case and to compare it with the existing technology. At the beginning of the thesis are described the basic characteristics of the bushings and the use of the worm housing part produced by Wikov MGI. In the next part, attention is paid to the current technology of production and its evaluation. The practical part includes the choice of the machine, the clamping mechanism and the tools necessary for making the part. The last chapter of the thesis compares three variants of the technological process, in terms of time-consuming operations and economical advantage for Wikov MGI.

Technology of product machining on CNC machines
Brázda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.

Technology solutions with a CNC machine
Baklík, Lukáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with the production of rotary component (master shaft). In the first part is selected suitable semi-product for the specified component, followed by the assignment of production machines and choise of the appropriate tools. Covered is a technological process, capacitive calculation of VBD and energy consumption including respect for the ecology of production. In the next part the NC programs are created in the control systems called Yasnac and Heidenhain iTNC 530. The final part is devoted to the production of the specified component.

Production of Pattern Equipment for Casting Pump
Suchomel, Martin ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on the design of foudry technology, design and production of pattern equipment for castiong of pump from cast iron ČSN 42 2420. The practical part elaborates design of technology and pattern equipment in CAD system SolidWorks. Simulation of casting was made in CAE system ProCAST. For design of milling technology was used CAM system HSMWorks. On the CNC machines was machined model, core box and underlay. Result of my thesis is pattern equipment for moulds and cores for the casting. In the end was made molds, cores and five samples of casting was casted.
