Production hinge saddle motorcycle
 Hanych, Libor ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborates the design of technology production of the hinge used for fixing saddle motorcycle. The hinge is manufactured from 1 mm thick construction sheet steel 1.0038 in production run of 50 000 pcs/year. A technology of shearing and bending at progressive die tool was selected from various options as the most suitable technology of manufacturing. Based on the literature study of shearing and bending technology, an optimal production process of hinge was designed. After technological, structural and control calculations the tool was designed and the technical documentation was elaborated. The eccentric press LKDR 200 made by ŽĎAS company was selected for the production. This press complies in terms of required forming force and the dimensions of the tool. Using the economic evaluation, the production costs for one hinge were calculated in the amount of 18,5 CZK. 35% profit of the company is included in the price. According to the calculated turning point, the production becomes profitable after 24 187 piece being manufactured.

The influence of the vibrations of the grinding spindle of the grinder on the vibrations of large shafts during machining
 Hanych, Libor ; Vlach, Radek (referee) ; Nahodil, Petr (advisor)
This master's thesis deals with vibrodiagnostics and its use for monitoring of the vibration transmission during grinding of large shafts at Siemens Electric Machines s.r.o. based in Drásov. Diagnostic system for machine tools testing was designed as well as a measurement methodology, which is used to detect the vibration transfer from the grinding spindle to the workpiece. Influences that affect the quality of the ground surface were determined, based on evaluation of measured data. The last part is dedicated to a proposal of a diagnostic and measuring system.
