Finishing milling of accurate surface
Šimonek, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The aim of this work is to find a suitable cutting tool and suitable cutting conditions for the production of hydrostatic surfaces of a crossmember with the quality of the surface structure of Ra 0.8 mm. The technology described in the thesis deals with finishing hydrostatic surfaces by milling, with the quality of the surface structure of Ra 0.8mm. As the production method cutting operations using CNC machines is used. To assure the quality of the surface insert tools are used, which are selected and evaluated based on experimental testing from six different suppliers. The technological process of production solves the problem of the hydrostatic surface production from the first gripping all the way to the final manufacture of the surfaces.

Pension PREMIER in Janov nad Nisou, implementation of finishing works
Pavlíková, Jana ; Nečasová, Barbora (referee) ; Kovářová, Barbora (advisor)
In the bachelor thesis I have dealt with finishing work on the top, where I focused on making plaster Hasit and construction of sauna. Plasters are made manually from before-spraying, the core of plaster and final stucco plaster. The construction of sauna lies in the design of the squared timbers. Insulation - PU boards is located among them. The final surface is made use of floorboards, which are made from Scandinavian spruce. The object for which I work processed, is located in a secluded spot in the village called Janov nad Nisou. This is of the changes to the existing layout pension Premier and his extension. As part of my bachelor thesis I'm dealing with technological stage on both objects at the same time.

New methods for inner rotary surfaces finishing
Kazdera, Tomáš ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
Content of the text deals with the methods of finalizing the internal surfaces of revolution. The paper discussed the theory most widely used machining methods that are commonly used in engineering practice. For each methods, are given the tools achieved surface roughness and geometric tolerances. The instruments are assigned to the machine on which the finishing operations are undertaken.

Thermomechanical Stress of Lead Free Solder Joint
Libich, Jiří ; Šandera, Josef (referee) ; Starý, Jiří (advisor)
This diploma thesis deals with the reliability of lead-free solder joints at a different interconnection structures. The first goal is to design the test cases shape BGA (FC) for testing the strength of lead-free solder joints at shear test in link with design of measuring method to detection shear strength during isothermal aging of lead-free solder joints. Following this shear stressing is investigating influence material and process compatibility, ie. pads finishing, material of solder and integrate of temperature (this mean thermal energy supplied during soldering) to lead-free solder joint strength.

Adjustments Shearing Procedure Tools
Dziuban, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This thesis explains how to determine and eliminate the causes of quality problems in the production of connectors and small electronic components for the automotive industry. The process of making these components is carried out by use of both high speed and low speed metal stamping presses. There are descriptions of the different designs of editing punches, stamping dies, trimming and molding tools and how unplanned issues can occur during the production process. It addresses all the customer requirements for quality end products, listing the type of material, finishes and technology used for the production of individual components as well as their functionality, durability, and economic impacts. All examples of changes in the design or technology of metal stamping presses are based on many years of practical experience and most of them can be successfully applied in other similar type of instrument production.

The Issue of Shot Peening
Lánc, Kryštof ; Daněk, Ladislav (referee) ; Peterková, Eva (advisor)
The thesis is primarily focused on theoretical processing shot peening technology, which belongs among the finishing operations using plastic deformation. The thesis is primary focused on describing basic principle of shot peening, sorting shot peening machines and abrasives, the principle of optimization of controlled shot peening and the related tests. The document also contains a methodology of creating educational material for operators of shot peening machine.
