本文首先介绍了Jaeger 的移动热源热模型图,切断磨削热模型图和蠕动进给磨削热模型图。在此基础上论述了高效率成型磨削时的热源分布与热传导情况。由于磨削时的热损伤引起工件的表层变色,而金属表面层的变色与加热温度有直接关系,并影响到工件材料的性能,故本文通过试验观测到工件热损伤时的变色情况,得出了各种因素对工件热损伤时的影响,然后应用热模型图的热源分布与热传导原理对试验结果进行了分析。
This paper first introduces Jaeger’s mobile heat source thermal model diagram, cut off the thermal model and creep feed grinding thermal model diagram. On this basis, the heat source distribution and heat conduction during high-efficiency profile grinding are discussed. Due to the thermal damage caused by grinding the surface of the workpiece discoloration, and the metal surface layer of the discoloration and heating temperature has a direct relationship, and affect the performance of the workpiece material, so this article through the test observed when the workpiece thermal damage discoloration, come to The influence of various factors on the thermal damage of the workpiece was analyzed, and then the test results were analyzed with the heat source distribution and the heat conduction principle of the thermal model.
