Evaluation of lubricants for forming
Svobodová, Hana ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The aim of this diploma thesis is experimental testing and evaluation of the suitability of lubricants for drawing stainless chromium - nickel austenitic steel X5CrNi18-10 and comparison of the results obtained from the work [51]. The testing was performed by modeling the friction between the traction edge and the retainer, which corresponds to the real production process at ACO Industries. The introductory part of the thesis describes the process of deep drawing, followed by a description of tribology and the effect of friction. The individual types and properties of lubricants are described in more detail. The main part of the work deals with the testing of lubricants. The results are then described and evaluated.

Measurement of roughness of the laser cutting edge
Drábek, Michal ; Šknouřilová, Eva (referee) ; Mrňa, Libor (advisor)
This bachelor thesis deals with laser cutting technology. The thesis is divided into theoretical and practical part. In the theoretical part is described the basic principle and function of the laser and the distribution of different types of lasers. Descriptions of each use of lasers in the engineering industry follow, more attention is mainly devoted to laser cutting. In the experimental part is presented a methodology to measure the roughness of the test samples which were cut from stainless steel X5CrNi18-10, the subsequent evaluation of the roughness parameters and comparison with the norm ČSN EN ISO 9013.
