Abstract
A method of detecting grinding cracks during the grinding process has not yet been developed in fine ceramics. The objective of this study is to example whether grinding cracks, which are generated during the grinding process, can be detected in-process by monitoring the acoustic emission AE. AE signals, which were detected during grinding, have been analyzed and compared with the signal before grinding cracks are generated. AE between 1.0 - 1.2 MHz are detected when grinding cracks are generated, while they are not detected when grinding cracks are not generated in fine ceramics. By utilizing this relationship. it becomes possible to detect grinding cracks in-process.
