ANALYSIS AND CONTROL OF VIBRATION IN GRINDING

2019-4-21  Vibration in grinding machine is hard to measure. It is witnessed from the formation of waviness on the work piece and grinding wheel. The major causes of vibration in grinding machine are misalignment and unbalancing. These unwanted vibrations will reduce the life of both machine and tool, resulting in loss of production. Vibration measurement is done by different approaches. This paper explains the vibration measurement done by Vibrometer. The vibrations are minimized by introducing dampers, made of rubber. The vibration

Measuring vibration on precision grinding machines

Self-excited vibration occurs only during grinding, due to grinding parameters, the process, and certain machine characteristics such as natural frequencies of the machine. During grinding, undulations/waves can start to form on either the workpiece or the grinding wheel as fluctuating forces excite a natural frequency on the machine.
