The machine industry has undergone several developments in the past years, and reducing the cost and time required for machine designing is important. In this study, the vibration characteristics of a precision grinding machine were obtained through experimental modal analysis and finite element analysis. The experimental modal analysis employed single point excitation, and the equipment used

Aug 26, 2014 [Inaskai and Yonetsu 1969, Gawlak 1984]. Hydraulic systems installed in grinding machines will also cause Forced vibration. Floor vibration is also a source of vibration. 1.2.2 Self – Excited Vibration These vibrations are caused from the cutting process in grinding machines. Regenerating effect is the main cause of this vibration

Dec 15, 1998 But in most cases, it is not practical to remove all harmful forcing functions from the grinding machine. This situation exists because many of the sources of harmful vibration actually emanate from the grinding machine itself. Examples include hydraulic pumps, drive dogs, and worn spindle bearings, just to name a few
