Abrasive water jet machining of hard-to-machine materials
Kubín, Matěj ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The diploma thesis deals with unconventional technology of material separation by water jet with abrasive. It describes the influence and specification of technological parameters of the water jet on the quality of the cutting surface. The work contains an experiment, where the aim was to achieve from the theory the influence of tech-nological parameters on surface roughness on composite materials from glass fiber and carbon fiber.

Unconventional Technology of Laser Cutting
Indra, Jaroslav ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis deals with the technology of laser cutting. The beginning is concerned with a general description of laser technology and laser division into basic groups. Next part refers to possible industrial use of laser beam, especially for cutting. Other chapters deal with the components suitable for the manufacture of this technology, technical preparation of production and the proposal to increase manufacturing flexibility when changing products. The last part is devoted to technical and economic evaluation.

Proposal of suitable technology for manufacture of the part "foot column"
Langr, Aleš ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
Master's thesis, elaborated within Master's degree, submits a proposal of suitable technology for manufacturing “column foot“ part, which attaches filtration unit to the ground. Material is 6 mm thick sheet steel in accordance with ČSN 41 1375 norm. Run (/production batch) of the part is 4 000 pieces per year. On the basis of literary study about unconventional technologies for flat sheet metal production 3 technologies were suggested: plasma cutting, water jet cutting and laser cutting. These technologies were technologically and economically analyzed. At the end thesis evaluates whether purchase of respective machine would pay out for the firm or they should continue to buy parts from cooperation company.

Unconventional production technology of chains
Hostinský, Michal ; Mrňa, Libor (referee) ; Osička, Karel (advisor)
Unconventional technologies and their continual development brings along new possibilities in the manufacturing process. The submitted project is focused on solving problems in the procession of sheet metals in the manufacture of special parts of roller and conveyor chains. In the assessment of the technology of components, laser cutting was evaluated as the most optimal technology. With this goal, there was a public tender in terms of the purchase of a new machine designed for the manufacturing operations of the company of RETEZY Vamberk. This company ranks among the most major manufacturers of conveyor, roller and special chains in Europe.
