The options of production of holes at the tube wall
Vysloužil, Oldřich ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The topic of the bachelor thesis deals with processing and forming of profiles (tubes). In the thesis, the most well-known methods of making a hole in the wall of the tube such as drilling, cutting and milling are introduced. The work is further supplemented by some of the unconventional methods such as Flowdrill, T-drill, or currently the most required machining today – laser cutting. Basic technology process is described for each method, as well as examples of tools and machines are presented. In the end, complete evaluation is presented in the form of an overview of advantages and disadvantages.

Manufacturing of a shift fork of a motorcycle
Vysloužil, Oldřich ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
This master´s thesis deals with the design of production technology of the shift fork in the gear box in a Jawa motorcycle. The 16MnCr5 (1.7131) basic material, with its thickness of 2.5 mm, was chosen for production of the bent sheet metal part, which is going to be subsequently heat treated. As the most suitable production method for the given series of 25,000 pcs. per year, was selected production method in the compound progressive tool, which combines shearing and bending. To select forming technologies, a short study of literature was made, which was supplemented by determination of the production process. The calculations, which were needed to verify the technological conditions, were made for the selected the manufacturing process of the part and also to select the machine. An APA-60 type eccentric press was chosen according to the determined total forming force. The machine is supplemented with a device that nebale production automation, which is an unwinding stand for a scroll metal sheet and a step feeder. At the end, a description and visualization of the tool is presented.
