Solution technology of two groove guide pulley production.
Pokladník, Robert ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Technology compiling two groove pulley making for two types of billets. As a billets is used in both cases a cast iron EN-GJL-250. The technological process solves production of both variants from designing the billets to trans-mission to the storeroom. The production is realized through cutting operation by CNC machines. The tools are selected with cutting tip. Finaly both variants are compared from economical perspective.

Manufacture of centrifugal Castings from iron and non-iron alloys
Žanda, Miroslav ; Kaňa, Václav (referee) ; Cupák, Petr (advisor)
The thesis describes and characterizes the foundry method of centrifugal casting, which was established in the 16th century. Based on a literature study of centrifugal casting and centrifugal force, the principle of centrifugal casting is described. Centrifugal casting can be divided according to the position of the axis of rotation to horizontal and vertical or by the method of right centrifugal casting, semi-centrifugal casting, centrifugal casting, or Tekcast method. The most basic and most common centrifugal casting product is a pipe. The pipe production is progressing from material melting, pre-operation machine preparation, casting and solidification of the melt, to adjusting and finishing of the pipe. We can cast centrifugally a several of materials, especially steel, cast iron, copper, zinc, aluminum and titanium. Centrifugal casting can also cast multilayer castings.

The flat new building
Vaněček, František ; Sedlák, Radek (referee) ; Beneš, Petr (advisor)
The proposed apartment building including a fixed level pavement, parking spaces and a driveway is situated on land number 723/213 and 723/184 (farm land) which is located in the southeastern part of the town Horní Stropnice along the main road towards Trhove Sviny. The apartment block has been designed as a four storey building for small and larger families in 14 seperate apartments (4 apartments each on the first, second and third floors and 2 apartments, hair salon and office on the ground floor) without any basement. The key construction feature is a wall system based on basic bands of simple concrete with a concrete mounted ceiling and a roof truss with gable roof tiles at an angle of 35°. There will be 14 apartments in total (14x 3+kitchen unit). The apartment windows will have sufficient sunlight and silencing. The main entrance, covered with a concrete porch roof, will be west facing. Each apartment will be constructed around the entrance foyer, which connects the main living quarters consisting of a combined kitchen dining room, living room , toilet, bathroom, (including bath, sink, washing machine), bedroom and one or two children's room, (depending on the size of the apartment). Ground floor terraces and 1st to 3rd floor balconies will be accesed via the living rooms. There will be a technical room on the ground floor which will have two gas boilers, a hot water cylinder, central heating distribution, sewer and some individual storage space for each apartment. The space under the staircase will serve as storage for prams or bicycles. The hair salon and building office will be built in the entrance foyer, which will include a public convenience for visitors and an entrance to the visitor's waiting room, guest rooms, individual work rooms all of which will be ready for use. A new asphalt road will enable access to the new apartment block and the neighbouring apartment block on land number 723/13.

Making sand moulds and cores for casting
Katrňák, Jiří ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
Bachelor thesis describes various methods for the production of sand molds and cores in foundry and basic concepts associated with this issue. Due to the large number of production methods are described only basic and most widespread methods. The work includes the design and manufacture of cast-iron grate for the stove, made into a mixture of bentonite and self-hardening mixture AlpHasetTM.

Manufacture of cylinder head casting for engine renovation Jawa 50
Pastyřík, Petr ; Myška, Martin (referee) ; Bořil, Petr (advisor)
This project elaborats the manufacture of a cylinder head casting for an engine renovation of Jawa 50. Based on the literary pursuit of suitable foundry technologies and using 3D printing in foundry a casting production technology was designed and the cylinder head was made. The part was designed in the CAD software and then printed on a 3D printer. The printed model was formed in ceramic shell form, then melted and the form was annealed. After that the cast was casted. The last operations were fettling and finishing machining.

A Control System for Applications Testing in Linux
Beneš, Eduard ; Vojnar, Tomáš (referee) ; Smrčka, Aleš (advisor)
This thesis discusses the area of a control system for application testing in Linux. There is a need for testing software and its quality using automated software tools. Huge number of testing tools is available, Red Hat Test System (RHTS) being one of them. Dierent approaches to classi cation and evaluation of a testing tools are presented. Selected software testing tools were evaluated and compared with RHTS. The thesis then presents a design of a system for non-interactive application testing in Linux with support for RHTS tests and with focus on future enhancements. Implemented system is nally tested using proposed set of tests and several usage examples are described.

Hydraulics forceps for heavy manipulators: compare of design welding or casting constrution
Burian, Viktor ; Šubrt, Kamil (referee) ; Knoflíček, Radek (advisor)
This bachelor´s thesis discusses forging manipulators and their use in free forging. It describes principle of functionality and structure of these machines, which serves as a special accessory for forming machines. It describes the construction technology of casting and welding structures. It executes proposal of casting and welding construction pincers for selected load capacity and the basic design calculations are made according to this proposal. Then, these structures are evaluated in technical and economical view.
