Detection of Grinding Temperatures Using Laser Irradiation and Acoustic Emission Sensing Technique

This article lays down the foundation of a novel method for the detection of grinding thermal behaviours using a laser irradiation technique. The novelty is that the laser irradiation induced thermal AE signals can represent grinding thermal behaviour. It proved, for the first time, that grinding stresses can be analysed separately in terms of thermal and mechanical sources. The method led to further developments in process monitoring techniques for use in the aerospace, Rolls-Royce, and nuclear energy industry, Y-12 National Security Complex, USA.
