Abstract: This study proposed a prestressed micro-grinding to the plate edges to induce a significant temperature rise in the edge crack-prone zone. The objective was to investigate the temperature rise effect of AZ31 magnesium alloy plates under varying conditions of prestress, micro-grinding depth, and grinding speed. A finite element model of prestressed micro-grinding was established to analyze the temperature evolution characteristics in the grinding zone over time, both along and across thickness directions. Mathematical models of the maximum temperature in the surface layer and the depth of the temperature rise area were established. The results indicated that the grinding temperature shows a sharp gradient downward trend along the thickness direction during the grinding process. The surface metal reaches peak temperatures between 338.46 and 429.71 ℃ within 3 s, positively correlated with grinding depth but negatively with grinding speed; it initially increases then decreases with higher prestress levels. The depth of temperature rise region in thickness direction under different loading conditions ranges from 178 to 240 µm near the surface layer, positively correlated with both prestress and grinding depth while negatively correlated with grinding speed. Additionally, the prestressed micro-grinding process will form a certain thickness of fine crystal layer in the grinding surface layer. [ABSTRACT FROM AUTHOR]
