The machining test with a surface grinder was carried out on new ceramics to investigate the relation among AE, grinding force and machining integrity. As a result of fundamental test, both amplitudes and continuous-times of AE signals were distinctly affected by the difference of base materials in which the AE sensor was mounted. In grinding test, the distinguishable amplitude of AE took place in coincidence with the place of the slit of test pieces, which was considerably higher than that of the bulk. In the case of new ceramics, the order of the magnitude of the amplitude of AE showed the opposite tendency compared with that of the grinding force Especially, the integrity of sialon was superior to that of WA and 2A, in correspondence with the degree of the AE count numbers.
