Abstract
Grinding is a widely used process in metalworking and other industries, where the quality of the finished product is highly dependent on the grinding wheel's condition. Monitoring the condition of the grinding wheel is, therefore, crucial to ensure dimensional accuracy, quality and to reduce manufacturing costs. Acoustic emission (AE) sensors can provide real-time monitoring of the grinding wheel condition by detecting the acoustic emission signals generated during the grinding process. In this study, a methodology to measure the radial grinding wheel wear through AE sensor is presented and the results are compared with the traditional imprint method. An experimental rig allows measuring the radial grinding wheel wear through an AE-based contact recognition procedure. The coordinates of the grinding tool periphery are saved on the numerical command of the grinding machine. After the measurement, the saved coordinates are compared with the coordinates measured on the effective width of the grinding wheel after grinding experiments. The radial wear was calculated by the difference between the saved coordinates. Results showed a good correlation with the AE method and the imprint method. The proposed monitoring method can provide real-time feedback on the grinding wheel's condition, enabling manufacturers to make informed decisions and optimize their operations.
