Machining of the gear-box casting on a CNC machine
Hložek, Milan ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The master’s thesis focuses on the machining of a chosen gearbox on a CNC machine. The theoretical part deals with gearboxes in general and the aluminium alloy from which a selected gearbox is manufactured. In the practical part, the machining of the gearbox is proposed according to the corresponding drawing. Gradually suitable machines are selected, then depending on their limits, clamping devices are designed, next a set of tools is selected and an NC program is generated. The technological process of production is proposed and the basic production costs are calculated.

Sinumerik tools for programming of rotational machine part
Slavík, Daniel ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This diploma thesis deals with a manufacture of rotating mechanical component on CNC lathe machine with Sinumerik control system. At first the chosen component is briefly described and then NC program is created in Sinutrain Operate 4.5 system. Afterwards the program is verified by simulation. Within the diploma thesis a technological documentation is elaborated that contains a new technological course of manufacture and a manufacture drawing of the component. The final part of this thesis is focused on technical-economic evaluation of newly designed manufacture with verification of cutting conditions and required output of the CNC machine. The outcome of the thesis defines an hour rate of CNC lathe and price of component that regards to newly presented manufacture.

Machining of rotating Body-part on CNC lathe
Dlouhý, Vít ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This master's thesis is focused on the technology fundamentals of machining for the use of the CNC lathe which was used for machining the required parts are made of stainless steel. In the introduction are mentioned the historical milestones related to machine tools. In the following chapter is analyzed machining process and related fact. A follow-up chapter contains the parameters common to a modern machine tool CNC machines. Followed by the practical part with the characteristics of the machined components. The next chapter includes a selection of CNC lathe for production. Continued by selecting the appropriate cutting tool and adjusting the machine for the given component. They were applied a total of three variants of production with the subsequent evaluation. In conclusion, it became established fact, for example, the advantages of the shape tools or the use of more spindles during the machining.

Draft of design and manufacturing technology for the enduro footrests
Vrzal, Jan ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The diploma thesis is focused on draft of footrests for endure Honda Transalp XL700V of 2008. Attention is paid to the draft of the design of the footrest which is, which is designed for driving in light off-road. There is also described the issue if the choice of the material from aluminium alloy and the verification of the methods of the designed geometry using FEM and Rapid Prototyping. The experimental part deals with the design of appropriate tools and cutting conditions and with the creation of the NC program in ShopMill. There is enclosed the technical documentation and the NC program in the final part.

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.
