To investigate the effect of microscale grinding on the quality of ITO conductive glass, this paper conducted microscale grinding experiments on ITO conductive glass. The influence of process parameters on machining quality was analyzed using microgrinding force, surface roughness, and sheet resistance as indicators. Meanwhile, soda-lime glass was set as the control group to analyze the effect of ITO film. The results indicate that brittle fracture is the main removal method for ITO films, and the glass substrate exhibits two different removal methods, brittle and ductile, depending on the process parameters. The ITO thin film layer suppresses the sheet deformation of the glass substrate, increasing the grinding force and reducing the processing quality. Increasing the spindle speed, reducing the feed speed, and reducing the cutting depth can improve the machining quality. The spindle speed has a significant impact on surface roughness, while the cutting depth has a significant impact on the sheet resistance of the thin film. In addition, soda-lime glass chips mainly appear in powder and granular form, while ITO conductive glass also has flaky thin film chips generated by interlayer fracture. [ABSTRACT FROM AUTHOR]

To investigate the machining mechanism of silicon carbide (SiC) ceramic materials, this study utilized sintered diamond tools to perform drilling and grinding simulations on the material and developed a drilling model for SiC ceramic materials. By analyzing parameters such as surface morphology, stress, and cutting force, the material removal mechanism of SiC ceramic materials was revealed, and the effects of drilling parameters on cutting force, torque, and residual stress were studied. Experimental results indicate that during the abrasive cutting process, the hard contact behavior of irregular abrasive grains significantly affects material removal, leading to failure forms such as chip collapse, hole and groove cracking, and crack propagation. With an increase in the feed rate of the abrasive grains, the drilling force shows a certain range of growth patterns. The axial force is positively correlated with spindle speed and feed rate, with the feed rate having a more significant impact on the magnitude of the axial force. Additionally, as the feed rate increases, the torque also increases. The radial residual stress mainly manifests as residual tensile stress. [ABSTRACT FROM AUTHOR]
