Sinumerik 840D tools for programming of nutcrackers
Kundela, Miroslav ; Kubík, Roman (referee) ; Polzer, Aleš (advisor)
This thesis is engaged chip machining using the system Sinumerik 840D-ShopTurn. The first part of the thesis is engaged the incorporation of the control system Sinumerik 840D - ShopTurn among other control systems. The thesis also deals with the basic methods of NC programming with an emphasis on workshop-oriented programming. The practical part includes design and preparation of technical documentation for the selected part (nutcracker), including creating a CNC program using workshoporiented environment - Sinumerik 840D ShopTurn. The program was validated using a graphical simulation software SinuTrain 7.5 and also directly at the machine SP 280SY. At the conclusion was created techno - economic evaluation of the proposed technology.

Wood - structural material, its structure and mechanical properties
Kundela, Miroslav ; Hutařová, Simona (referee) ; Klakurková, Lenka (advisor)
The aim of proposed work is focused on the classification of wood using several different perspectives. Especially, with focus on its macro-, micro-structure (plant cell, wood cell and anatomical structure), chemical composition, physical properties (density, thermal properties, moisture, sound and electrical) and mechanical properties (strength, hardness and technological properties).
