Detection of High and Low Temperature in the Grinding Zone using Laser Irradiation Technique

Grinding burn is a physical phenomenon related to the temperature in grinding zone. This paper presented the detection of high and low temperature in the grinding zone using laser irradiation technique. Two experiments on temperature rise were carried out using laser irradiation and grinding separately. By controlling the laser energy flux and irradiation time the temperature rise can be manipulated. The acoustic emission signals generated during laser irradiation provide signature for monitoring grinding temperature. An ANN model developed based on thermal AE data extracted from laser irradiation was used to detect the thermal AE signatures in grinding experiments, so that the high and low temperatures in the grinding zone can be monitored. Such technique can be used for grinding burn detection. The grinding experiment arranged to identify burn or no burn signature of AE data due to high and low temperatures under given depth of cuts (1.0 mm and 0.1 mm).
