Utilisation of innovative materials at design of bohring machines
Tobolka, Ondřej ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
Thesis solves an issue of application unconventional materials used in horizontal boring machine design. Chosen problem is solved step by step from general selection of suitable material for supporting structure. The selected material is applicated on WFT 13 CNC machine design from production of Fermat and it is created 9 conceptual options of machine’s frame. Finite element method is used for analysis of conceptual options. Based on data from analyses, the best option is selected for constructional part with use of multi-criteria PATTERN method. Constructional part of thesis elaborates on the design of selected conceptual option and gives recommendation for essential processes used in development and production of sandwich structures. The master’s thesis comes with new construction solution for supporting structure of selected machine and especially insight in development and production of new unconventional materials in horizontal boring machines design.

Service platform of boring machine
Šebela, Michal ; Hulánek, Martin (referee) ; Brandejs, Jan (advisor)
The Diploma’s thesis deals with a construction design of a service platform for a horizontal boring machine. Input parameters are cabin dimensions, length and velocity of lift and shift. In the first part of the thesis is design arrangement solved. The lift is solved by a rack and a pinion. By the lift is drive design and gear calculation performed. Shift of the service platform is done by toothed belt. Air distribution with pneumatic parts choice is included in this thesis. Next part is divided to supporting frame and cabin design. It is made by welded profiles, in which a stress-strength analysis is performed. The last part of the thesis is divided to linear guide design. A part of this thesis is a drawing of an assembly facility and a movie about this service platform in a real service.

Safety assessment of operator activities for WHN 13 CNC horizontal boring machine
Nohavica, Radek ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma’s thesis deals with the current state of requirements for products resulting from directives of the European Parliament and the European Council. The aim of the thesis is a system analysis of the issue, proposal and justification of the chosen procedure for solving the objectives. Furthermore, the analysis of requirements of current standards and safety analysis related to the work of machine operators in the areas of operation, service and maintenance of horizontal boring machine WHN 13 CNC. The analysis is followed by a proposal for preventive measures for hazards where the value of risks and criticality is unacceptable, leading to their reduction.
