Manual production of damask steel knives
Žilinský, Martin ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with the production of damask steel and the subsequent manufacture of a knife. The theoretical part contains a technical description, the history of Damascus steel and its current use. The practical part includes a detailed design of the knife's own prototype, the technological process of damask steel production, grinding the shape of the knife, its heat treatment and making the handle. The result is the realization of the production of a damask knife according to the chosen technological procedure and the evaluation of the resulting prototype.

Manufacture of knives and their heat treatment
Bukvic, Tomáš ; Doležal, Pavel (referee) ; Němec, Karel (advisor)
This bachelor thesis deals with manual small series production of knives. It presents an overview of used cutlery steels and ushers their characteristics. It deals with the choice of blade geometry and material for a particular knife application. Furthermore, it initiates into the issue of heat treatment of knives, which is absolutely necessary for their functionality. The conclusion includes the documentation of the kitchen knife manufacturing process, which was made for the purpose of this thesis.

Calculation of heat and force field UniGear ZS1
Mokrý, Lukáš ; ABB, Drahomír Tůma, (referee) ; Dohnal, Petr (advisor)
The aim of my work is to describe high-voltage switchgear type UniGear 500R, which is part of UniGear switchgears family. I will focus on heating issue of one 500R unit and its parts during operation. Maximum values of this heating is limited by standards and can´t be exceed to ensure safe and reliable operation. That is why the heating tests are necessary part of designing and developing switchgears. Calculation will be made by two different ways. First is classic one-pole heating net method and second is numerical simulation in Solidworks flow simulation program. Except the theoretical description there will be presented also used 3D model and explanation of both method, used to calculation and simulation. Last point of this work is measuring of this type of switchgear and getting real data. The main point there is to compare measured values with values calculated and decide if is possible to simulate tests with appropriate accuracy. Then would be also possible to substitute the real test in laboratory, which costs many thousand crowns and takes lots hours of time. This work is collaborated with EJF division of ABB Company, where I am employed. Heating issues in this company is always on process, because of developing and improving of their products. So this work could be helpful in this field. ABB provides all materials needed, especially technical catalogues, 3D model and final values from laboratory measuring. Support from college faculty is mainly in study consultations and proposing of calculations making. In the end of work will be make final comparison and evaluation of achieved results.

Unconventional methods of processing materials for knives
Bražina, Jakub ; Němec, Karel (referee) ; Doležal, Pavel (advisor)
This thesis focuses on the issue of unconvetional cutlery materials, their application for production, and the processing of a hunting knife. The readers are aquainted with cutlery issues in the search section, where the basic characteristics and properities are written. The next part describes the various metallic and non-metallic materials and their possible properities of processing and production. This thesis also deals with the surface protection of these cutlery materials. The second main part describes construction design, material selection, heat treatment, and with surface treatment of the hunting knife.

Increasing production effectiveness of recycling blade
Kalenda, Jaromír ; Fiala, Zdeněk (referee) ; Zemčík, Oskar (advisor)
The focus of this thesis is the manufacturing of a waste processing knife from DIN 1.2379 steel. The first part of the thesis defines the man hours required by the current standards and describes the actual man hours used at Pilana Knives s.r.o. The next part deals with the original technical procedures of the manufacturing process. The last part of the thesis proposes and analyses a new and more efficient procedure. The thesis concludes with an assessment of the technical procedures and the total manufacturing cost savings.

Production of Knives
Suchý, Jan ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This theses deals with cold weapons topic. The first part describes historical development of European swords and weapons originating from them. Further on the thesis presents material analysis and comparison of steels used for cold weapons production. It also shows different production methods including a brief note about the difference between forged and gringed blade. Then the thesis outlines differences among various blade shapes and how these shapes define their cutting characteristics and usage. The closing part of the thesis deals with blade geometry and grinding technology.
