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.

VIBRATION IN GRINDING OPERATIONS

- negatively affects the machine life and intensive sound. There are 2 types of vibration in grinding operations: forced and self – excited. Eccentricity and non – alignment of grinding wheel are the main reason for generation of forced vibration. Regenerative effect takes responsibility for formation of self – excited vibration.

ANALYSIS AND CONTROL OF VIBRATION IN GRINDING MACHINES

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.
