Use of Unconventional Method WJM in Condition a Small Firm
Masařík, Adam ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis is focused on the possibility of using the technology of water jet for stack cutting. The theoretical part deals with two types of water jets used for cutting materials and their appropriate and inappropriate application. It also includes a description of basic elements of a water jet cutting machine. In the practical part of this thesis a few samples of a component are made by abrasive water jet stack cutting. The impact of this cutting method on production costs and cutting quality is assessed afterwards.

Water Jet Cutting
Odehnal, Ondřej ; Fic, Miloslav (referee) ; Kárník, Jan (advisor)
The following bachelor’s thesis deals with an unconventional technology of waterjet cutting. Content of the thesis is focused on the description of the technology, basic classification and description of utilization methods. Machinery used in this technology is described below. At the beginning, this work introduces the history and describes the principle of the water jet. Following is the classification of the methods used for water jet. The most important components of devices operating with this technology are described in the next section. The last part is the description and evaluation of an experimental verification of theoretical knowledge. The quality of cut and the behavior of the water jet was examined for different cutting parameters on cutting samples. Evaluation of the thesis is included in the conclusion.

A COMPARISON OF THE WATER JET CUTTING AND LASER TECHNOLOGIES
Chamrad, Jakub ; Zlámal, Jan (referee) ; Píška, Miroslav (advisor)
The thesis is focused on the introduction of non-conventional technology into the manufacturing workplace, mainly water jet and laser cutting. The first two chapters are research about water jet machining and laser. A practical part of my thesis was carried out with the assistance of Honeywell and involved comparing the efficiency of an older laser cutting machine against and new one for water jet machining.

The Use of a Waterjet Technique in Finishing Operations
Jantač, Marek ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with abrasive waterjet cutting. In the first part we dis-cuss the possibility of using an abrasive jet in various industries, its advantages and disadvantages. Furthermore, abrasive jet machining methods such as cutting, turning and milling. Then focuses on the technology at AWAC company, which were cut off samples for subsequent measurement. The aim of the measurements was to determine and compare the surface roughness of the samples were cut at different parameters.
