Thermal Models of High Efficiency Deep Grinding and Grinding Temperature

摘要

Three thermal models are developed for high efficiency deep grinding, they are respectively circular arc heat source model, uniform heat flux distribution model and triangular heat flux distribution model. Mathematics equation of every thermal model is expressed. The three models take account of the oblique movement of the heat source plane, which is particularly important for the conditions of high moving speed and large oblique angle of the heat source plane. With the solutions gained from the models the temperature at the grinding zone of high efficiency deep grinding is investigated. Grinding experiments are done. Experiment results show that the measured temperatures are in agreement with the calculated temperature approximately.
