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.
