Using of elastomers in forming technology
Drda, Ondřej ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The purpose of this graduation thesis is to investigate and summarize the usage of elastomeric forming, which represent a uniqe method of cold forming in which the elastomeric pads overtake the function of the solid part in a forming machine. The most distinctive feature of elastomeric forming is its low price and a wide range of usage. It can be applied also to metal materials with finished surface. However the major disadvantage of this method is the need of an enormous pressing force. The elastomeric pads fall into two main categories – the open and closed ones. The open type is mostly used for metal sheets bending and roll bending, whereas the closed type finds even greater usage in processes like shearing, drawing (Guerin stamping), deep drawing (Marform, Maslenikov technique) and radial expanding. The thesis further describes the elastomers´ technical features, deformation withstandings, forming principles and their general usage.

Design of CNC Milling Machine for Woodworking
Drda, Ondřej ; Zemčík, Oskar (referee) ; Slaný, Martin (advisor)
The thesis deals with the design of a CNC milling machine. The thesis includes a research of machines available on the market and a research of components suitable for the construction of the milling machine. In the next part, the calculation of motors, ball screws and linear guides was carried out. The work includes a complete 3D model and drawing documentation.
