Analysis of tool steel cracking and a study of its elimination
Tomešek, Viktor ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The aim of this diploma thesis is to describe the causes and mechanisms of degradation processes that affect the surface of tools made of tool steel and to design and verify a practical solution that would lead to higher resistance of tools to these processes. Chapters in the theoretical part deal with fracture behavior of the material and the possibilities of its elimination, the experimental part includes testing of the effect of coating on the durability of hot forming tools.

Design and Production of Clamps for Mandrels ISO 40
Tomešek, Viktor ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
Main aim of this bachelor’s thesis is to design and product clamp for mandrel ISO 40. This clamp will replace the other one, which is used in the milling workshop C2 on BUT Faculty of Mechanical Engineering. It will ensure easier and faster operator’s work during tool change. Also manufacturing process, selected material and cutting conditions are described in this thesis. Theory necessary for an understanding of the issues is stated in introductory section. In the final part, there is executed technical-economical evaluation with the overall costings associated with the production of the clamp for mandrel.
