Design of gantry-type milling machine
Mikulová, Michaela ; Sýkora, Jan (referee) ; Blecha, Petr (advisor)
This master´s thesis deals with gantry – type milling machines. At first gantry – type milling machines are divided according to their structure. Then basic parts of an upper gantry – type milling machine are described. This machine is designed in a calculation part of this thesis. A calculation of a cutting force, a calculation of a needed moment of a drive of a spindle and a feed screw for axis x, y, z, a design of a belt drive between the spindle and the drive are done in the calculation part. Then the model of this upper gantry – type milling machines is made. Drawings are created for some parts of this machine.

Monitoring of hazardous environment
Bilík, Martin ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
Diploma thesis Monitoring of hazardous environment deals with possibilities of construction of monitoring device for the nuclear power station Temelín. In the first part are accurate requirements for monitoring device, individual risks and identify obstacles and opportunities how to overcome them. There is also description of basic options for measuring temperature and environmental monitoring. Using multi-criteria analysis was done the selection of all components, from which is possibility to construct the first development release of monitoring device. 3D models for each component and the overall design visualization facilities were created in the programming environment of Autodesk Inventor. The conclusion provides an overview of the financial cost of the equipment is assembled
