Producing of artillery shell
Moravec, Zdeněk ; Forejt, Milan (referee) ; Lidmila, Zdeněk (advisor)
The diploma thesis deals with the technology of production of the body of an artillery shell caliber 155 mm from C60 steel. The part is manufactured in series of 100,000 pieces. Based on a literature study and materials, a technological procedure of drop forging was designed, taking into account the specific shape of the forging. The volume of the starting blank and the forming force were determined. A suitable forming machine was selected based on the magnitude of the forming force. The design of tools for punching operations and reduction diameters of sets of rollers for forging stretching was also performed. In the technical and economic evaluation, the material costs for the production of the entire series were quantified.

Quality Check of Text in Forms
Moravec, Zbyněk ; Juránek, Roman (referee) ; Zemčík, Pavel (advisor)
Purpose of this thesis is the quality check of correct button text display on photographed monitors. These photographs contain a variety of image distortions which complicates the following image graphic element recognition. This paper outlines several possibilities to detect buttons on forms and further elaborates on the implemented detection based on contour shapes description. After buttons are found, their defects are detected subsequently. Additionally, this thesis describes an automatic identification of picture with the highest quality for documentation purposes.

Barrel forging
Moravec, Zdeněk ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The thesis contains a description of basic specifics of small arms barrels. Further presents the overview of other production methods and describes the method of rotary swaging, its use in production of the small arms barrels and basic principles of forging machines. In the last chapter there is a general manufacturing process of general forged small arms barrel. The procedure includes a brief description of operations and a schematic images of selected operations.
