摘　　要：智能制造背景下,材料科学的发展与关键核心零件精密能级的提高,尤其是新兴高硬材料的广泛应用,对磨削精密加工提出新的挑战。磨削接触区的高温是束缚磨削高精度加工的核心要素。与此同时,降本增效、绿色环保加工的提出,推进了微量润滑技术在磨削加工领域的应用。本文结合磨削热生成机理与磨削表面强化换热机理,构建三维瞬态磨削温度场数学模型与数值仿真模型,开展高硬难加工材料微量润滑磨削的温度场仿真研究,为高硬难加工材料微量润滑绿色磨削冷却方法的应用和推广提供理论基础。Under the background of intelligent manufacturing,the development of material science and the improvement of the precision level of key core parts,especially the wide application of emerging high hardness materials,the new challenges to grinding precision machining are presented.The high temperature in the grinding contact zone is the core factor which astricted high precision machining for grinding.At the same time,the proposal of reducing cost and increasing efficiency and green environmental protection processing has promoted the application of minimal quantities of lubricant(MQL)technology in the field of grinding processing.In this paper,a three-dimensional transient grinding temperature field mathematical model and a numerical simulation model were constructed by combining the grinding heat generation mechanism and the grinding surface enhanced heat transfer mechanism.The temperature field simulation research of MQL grinding of high hardness and difficult machining materials was carried out.Which provided a theoretical basis for the application and promotion of MQL green grinding cooling method of high hardness and difficult machining materials.
