Solid carbide cutting tools are mostly manufactured by abrasive processes on tool grinding machines. In many situations, the first operation represents a cylindrical grinding of the blank. The manual preparation of NC programmes for this operation is especially time intensive in manufacturing of small series. Several manufacturers of control systems offer an integrated solution for cylindrical grinding, but these applications are closed and with limited flexibility. In this paper, a system for computer aided preparation of NC programmes for cylindrical grinding is presented. The tool path is calculated from the given contour of the workpiece, the form of the grinding wheel and additional geometrical and technological parameters.

Moderní řezné nástroje z rychlořezné oceli nebo slinutého karbidu jsou v současnosti vyráběny broušením na CNC nástrojařských bruskách. Protože se při programování těchto obráběcích strojů jedná o velmi komplikovaný proces, jsou jejich řídící systémy obvykle vybaveny programovacím rozhraním ve formě soustav tabulek, do kterých jsou zadávány jednotlivé parametry vyráběného nástroje. Protože tento systém programování není dostatečně pružný, jsou některé řídící systémy vybaveny možností načítat externí NC programy, s jejichž pomocí je možné vyrábět buď speciální nástroje, nebo modifikovat výrobní proces stávajících nástrojů. Protože při výrobě řezných nástrojů je nezbytné uvažovat s tvarem obalových ploch, které proces programování činí značně obtížným, je výhodné vytvořit matematický popis drah brusného kotouče, který umožní dráhy snáze modifikovat s ohledem na časté změny, které jsou nezbytné při konstrukci monolitního řezného nástroje.

The thesis Consumer basket of cycling tourists in the Czech Republic deals with the creation of the consumer basket, which includes common expenses of cycling tourists during their cycling holidays and cycling trips in the Czech Republic. As part of the work was carried out a survey among Czech cycling tourists, whose results are analysed in the work.

The thesis is focused on effects of cycle tourism on a destination. In the introductory chapters there is the basic cycling terminology explained, the most common issues are discussed, great emphasis is put on long-distance cycling trails. The main goal is to analyse how EuroVelo 4 a 7 influence tourism in Prague. By means of a questionnaire survey among cyclists - visitors to the capital - the general (cyclo)consumer behaviour is defined and the benefits (brought to the destination because of the trails) are expressed in numbers.

The diploma thesis is focused on monitoring of cycle tourism on a selected section of the Elbe route between the cities of Prague and Roudnice nad Labem. The main goal of the thesis is to analyse current situation on this selected section of the route and to find out about its economic benefits. The theoretical part consists of explanation of the basic cycling terminology and the subjects supporting the cycle tourism are also presented there. Additionally prospective possibilities of funding are introduced there. The last two chapters of the theoretical part are focused on monitoring of the cyclists and the product of the Elbe route. The practical part analyses the selected section of the Elbe route.

The diploma thesis evaluates the benefits of a section of the Elbe route between the city of Hradec Kralove and the village of Kuks. In the theoretical part, frequently used terms are explained, along with the history of cycle tourism, the Elbe route is introduced, as well as the subjects taking care of it, and the costs and benefits of cycle tourism are described. The practical part is focused on the mentioned section of the route -- it depicts this section and then moves to present and analyze the results of the survey conducted during this study.

The Master's Thesis deals with the problem of the development of cycling on Elbe Cycling Path. The theoretical part is explaining the basic temrs of cyling, functioning of financing and managing of cycling in the CR and finally The Elbe Cycling Path his introduced from the perspective of history and future developement. The practical part is focusing on particular section of the trail between Litoměřice and Ústí nad Labem. This section of cycling path is analyzed and it is also subject of individual survey. Eventually author proposes some measures to solve problems of Elbe Cycling Path, that could contribute to the developement of cycling on Elbe Cycling Path.

Cycle tourism presents for the Czech Republic an opportunity to address new touristic segment of relative higher purchasing power and attract tourists to regions. Cycle tourism presents also opportunity for economic growth in rural, often less developed, areas. It is one of the most popular sorte of sustainable tourism, which doesn't harm the enviroment. However, there are still reservers in the cycling infrastructure of the Czech Republic. The obstacles of getting investments for its development are missing economic arguments. The aim of this thesis is to design a method to quantify economic gains of cycling infrastructure. Based on the designed methodology, a large analysis of Greenways and long-distance cycling routes economic gains should take place.

Main goal of this work is to analyze the cycletourism from many points of view. The thesis has topics such as -cycleroutes -imports, exports and production of bicycles -financing of cycletourism -cycling in city -cyclist and his evaluation of services for cycletourism -greenways
