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.

Solution CNC technology of part whit a CNC-unit Sinumerik
Forbelský, Jiří ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis elaborates complete manufacturing process of a shape shaft. Technological procedure is designed in two variants. The practice variant employs tools, material and CNC lathe available at university workshop. The designed technological procedure has been verified by manufacturing the shaft. Series production utilizes modern tools and an industrial lathe. Both the described variants are compared and evaluated.
