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.

Classification of flexible manufacturing systems & machining centers
Selucký, Jaroslav ; Kalivoda, Milan (referee) ; Kubík, Roman (advisor)
This bachelor´s thesis is focused on analysis of the flexible manufacturing systems and machining centers. In the first section the basic characteristics of the flexible manufacturing systems and their versions are described. There´s also a description of the manipulators, conveyors and possible layouts of systems which are often used in the flexible manufacturing systems. The next section is focused on the description and classification of the machining centers as the main parts of flexible manufacturing systems. The classification is firstly done according to the design and technical possibilities and in the last section the flexible manufacturing systems are classified according the user´s requirements.
