Abstract

This paper deals with the automation of grinding operation. In this study, the developed equipment extracts the bending vibration sound of a grinding wheel using a microphone. And, the discrimination of grinding state is discussed based on signals obtained from the bending vibration sound of a grinding wheel. As a result, the sound pressure of the bending vibration sound becomes high at the specific frequency of a grinding wheel. The bending vibration sound can measure the normal grinding force, In short, the bending sound pressure level at specific frequency can replace the evaluation for grinding state. And, Contact sensing of 1mm unit is possible by observing the bending vibration sound. At last, the automatic cycle of a grinding processing by observing the bending vibration sound was proposed.
