Design of operator workplace of machining center
Kříž, Jan ; Pavlík, Jan (referee) ; Novotný, Tomáš (advisor)
The presented work contains the parameters and rules relevant for the design of the inter- face between the machining center and it's operator. All of information were obtained by search in scientific literature and technical standards and subsequently were sorted according to the elements to which they relate. The work contains the actual anthropometric dimensions, description of the interface elements with references to standards which relate to them. The study also shows an example of an optimized keyboard layout for machine tools and methods applicable to design the spatial layout of the workplace. In conclusion there is evaluate the state of currently available literature and technical standards.

Building and control of 5-axis milling machines
Hekrle, Pavel ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
This bachelor thesis deals with detailed description of acceptance tests of machining centers. The first part contains segmentation of geometric tolerances, which are used for geometric accuracy tests. A large part of this thesis is dedicated to these tests. The next part includes phases of preparations for acceptance tests as well as segmentation and progress of these tests. One part of the thesis is devoted to machine alignment. The last chapter contains detailed description and principle of some modern measuring devices which are used for acceptance tests.

On the production technology of a shaped part with multi-axis machining
Kopcík, Daniel ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The theoretical part of this thesis is introducing basic information in production of shaped components on CNC machines. It describes each steps from a design of the component to production. Main target is summarization of available modern technologies that can be used. Experimental part uses these modern technologies for processing design shaped component. It describes process of design 3D model part in CAD system, subsequently creation of program for machining in CAM system and solves production of part on CNC machine. The aim of this thesis is design part with interesting design and production difficult enough to represent company, where it was made.

Layout solution of the machining center producing the shaft component
Göth, Karel ; Osička, Karel (referee) ; Štroner, Marek (advisor)
The diploma thesis deals with the design of a machining center for a shaft-shaped component. For the design of the machine shop, it is necessary to obtain information from the production process and the drawing. This information, together with the number of pieces produced per year and the standard time for each machining operation, will allow the design to be carried out. In the first step, it is necessary to carry out capacity calculations, which will give us the necessary number of workers, machines, manual workplaces and production and non-production areas. Following this, it is necessary to place the machines on the production area based on the established method of arranging the machines. In addition to the production equipment, various other aspects of the production hall will also be located in this step, such as toilets, changing rooms, foremen's office, workshops, etc. It is necessary to ensure the optimal location of the individual parts of the production with the help of the Sankey diagram, which will allow us to visualize the material flow. The flow of material needs to be solved at multiple levels, namely inter-object transport of material, inter-operational transfers of material, technological operations with material and waste management. At the end, an economic evaluation of the proposed giant will be carried out.

Safety assessment of NHX5500 DMG MORI machining center
Novotný, Petr ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma thesis deals with legislative purposes for the operation of machinery in the Czech Republic and the European Union. It deals with the analysis of technical standards of machinery, specific machining centers. The analysis of the risky machining center NHX 5500 DMG Mori is based on this. The result of the work is the minimization of ongoing risks and meeting the legal requirements of the state of the operated machining center.
