Flaring the End of a Tube Under Static and Dynamic Conditions
Šrefl, Martin ; Samek, Radko (referee) ; Peterková, Eva (advisor)
The thesis is focused on expanding the ends of the tubes made of 1.4031 material into a cone shape for quasi-static and dynamic conditions. The aim of the research is the analysis of stress-strain condition in the area formed under the process conditions. As a technology test for expanding tubes is used a method of pushing the tube at a stationary mandrel and deformation measurement was done by 3D optical system ARAMIS. In the thesis is described in detail an experiment carried out under quasi-static conditions, the results of which yielded interesting findings. In the framework of the present study were designed and detailed engineering design and production tools designed for experimental realization of technological tests for quasi-static and dynamic conditions. Exploration in terms of the behavior of tube under dynamic conditions forming in this thesis is carried out in phase functional verification tools. The analysis of the forming process is planned in the framework of the next thesis.

Effective drilling tools
Šrefl, Martin ; Dvořák, Jaromír (referee) ; Humár, Anton (advisor)
The first part of this bachelor thesis is focused on the basic characteristic of drilling, dividing drilling tools from the point of view of construction and materials. Range of products drills with indexable cutting inserts domestic company Pramet Tools are compared with Range of products international company Sandvik Coromant in the second part.
