Abstract

The tribological phenomena that occur between abrasive grains and a work material are extremely complicated, and it is difficult to identify them. In this study, we focused on the change in abrasive machining performance under lubricated condition and investigated the possibility of in-process evaluation. Two AE sensors were attached to each test piece, and dual AE sensing of AE signals generated from each material was attempted. As a result of this experiment, it was found that the AE mean values of both test pieces decreased in the lubricated state compared to the unlubricated state. In addition, from the frequency analysis of the AE signal waveforms, it was found that the AE frequency component (about 0.1 MHz) due to friction increases.
