Cutting of materials using wasteless technologies
Voráček, Martin ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
Thesis contains literary review of wasteless metal cutting technologies. Technologies of shearing sheets, rods, bars and pipes are described, as well as laser, plasma and water jet cutting. The description of each of these methods consists of both physical principle and practical use, including examples of technological devices. Furthermore, main advantages and disadvantages of each method are discussed with regard to small batch or mass production.

Analysis of appropriate finishing technology after deep drawing
Šobáň, Pavel ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
This bachelor thesis summarizes information about appropriate finishing technology after deep drawing. The thesis is focused only on the most used and most proper methods, which include material parting operations, such as plate shearing, laser, plasma, water jet and saw cutting, and machining operations, such as lathe-turning and grinding. For each of the mentioned methods, a principle of the selected technology is described and also its suitability for the present problems. The thesis compares the individual methods considering their advantages and disadvantages for removal of uneven edges of cylindrical shells.

New trends of material cutting
Uttendorfská, Magdalena ; Špaček, Jindřich (referee) ; Peterková, Eva (advisor)
The thesis is focused on formation of a survey of modern methods of semi-product division in the area of forming technology. The first part of the thesis deals with material division conventional methods as cutting-off, clipping, refracting, cutting and sawing. These methods have already reached their utilization maximum. Their perfection is possible to be made e.g. by means of modern cutting materials. The next part is concentrated on material division special methods (oxygen cutting, laser, plasma and cutting by water jet) with presentation of their brief description. These methods have recorded the technology move ahead.
