Design of Tool for Louvers Production
Hejna, Jaroslav ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This thesis presents a tool design for production of embossments into the bottom part of the agricultural silo made of Dx51D material. The research analysis all technologies used for embossing, that is cutting and shallow drawing. This is followed by a chapter on simulation. The tool design itself is described. Its principle is based on tools for punching machines. The upper half of the tool is composed of a weldment to be clamped into pressing machine, into which are mounted functional parts in the form of inserts. The lower tool consists of several bolted plates, punches and a holding plate, which is located on the springs. In order to achieve correct design, necessary calculations were carried out and it was all confirmed by simulation in ANSYS. The two tool halfs are guided by pins attached at the edges of the lower tool. The technical - economical evaluation compares the work of the proposed tool with other possibilities of embossing.

Technological aspects of tools for wood machining
Brlica, Vlastimil ; Humár, Anton (referee) ; Prokop, Jaroslav (advisor)
The fully fashioned master’s thesis within the frame of the master’s study at the Fakulty of mechanical engineering deals with subject woodworking tools. There are characteristics of wood and tool materials used for woodworking. There is an emphasis on milling cutter in each case of construction of selected woodworking tools. Whereas there is concrete proposal of milling cutter used for production of half round profile – half round concave cutter – at the end of the thesis.

On the technology of tube scarfing
Řezáč, Matěj ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The thesis is focused on the technology of scarfing longitudinal welds in welded tubes. The theoretical part describes methods of production tubes. It also analyzes the method used in Mubea company. The experimental part presents the design of two innovative technologies of scarfing welds tubes, their experimental validation and subsequent evaluation. The experimental part also presents a design of the machine that must be produced for this operation.

On the deburring technology of a formed part
Žídek, Jan ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
This diploma thesis was created in cooperation with Mubea company. It deals with proposal of alternative technology of groove deburring. A special tool was designed for this technology and was experimentally tested. There are also tests for finding suitable cutting conditions, tests for appropriate tool’s positioning against a workpiece and tests for comparison the alternative technology of groove deburring to grinding technology included in this diploma thesis
