Study of the influence of process parameters on welding properties of ferritic stainless steel and carbon steel in laser oscillation welding
 Rýznarová, Martina ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
In the thesis, the influence of the shape of the beam wobbling geometry and the spot vibration frequency on the properties of the heterogeneous weld of X12Cr13 martensitic stainless steel with carbon steel S355MC in laser oscillation welding is investigated. Macroscopic control was performed on the samples, which were focused on weld size and heat affected areas, weld defects, weld shape and cant / drop face and weld joint root. Subsequent microscopic inspection determined both the weld metal structure and the heat affected area and base material. The last was a Vickers microhardness test. Based on the experiment, it was found that the spot process frequency is an important process parameter.

The technology of material division with grinding operations
 Rýznarová, Martina ; Kalivoda, Milan (referee) ; Prokop, Jaroslav (advisor)
This bachelor thesis deals with the technology of material division with grinding operations. The first part explains the basic principles and methods of use and advantages and disadvantages of technology of material division with grinding operations and other methods of dividing the material. The second part is focused on the characteristics of cutting tools and cutting conditions of division with grinding operations. In the last part, the measured unit machine time of the technology of material division with grinding operations and two other methods of dividing the material and wear of cutting wheels are compared.
