摘要：
Considering the interaction between any adjacent abrasive grains during the grinding process,the orderly arrangement of a single abrasive grain is studied,and an orderly arrangement strategy that can control the spacing of any two abrasive grains is proposed. After arrangement,each abrasive grain acts as a separate cutting edge on the surface of the workpiece,and the material is cut off successively to form grooves. According to the arrangement strategy,three arrangement methods are designed. The spacing of any adjacent abrasive grains is -50 μm,0 μm,and 50 μm,respectively,the arrangement template is prepared by electrochemical anode dissolution on the surface of the grinding wheel matrix,and the corresponding orderly arrangement of the grinding wheel is prepared by sanding electroplating,and thickening. At the same time,the grinding force and grinding temperature changes in grinding are calculated by grinding kinematic analysis,and the grinding force and grinding temperature in actual grinding are measured and analyzed by grinding experiment. The results show that under this test condition,the influence of feed speed on both is relatively independent:the grinding force is positively correlated with the feed speed,while the grinding temperature is negatively correlated with the feed speed. The grinding depth and the abrasive grain arrangement spacing comprehensively affect the changes in temperature and grinding force. When the abrasive spacing is small,the grinding temperature and force increase steadily with the increase of grinding depth;When the abrasive grain spacing is large,as the grinding depth increases,the two increase steadily and then slowly. © 2024 Hunan University.
