“…To understand the distribution of surface and subsurface residual stress under different cutting conditions to analyze the machined surface damage is very important. 27 Figure 9 shows the variation of subsurface residual stresses with different cutting parameters. It can be seen from Figure 9A, with the increase of the depth of cut, the maximum residual stress on the subsurface of the green ZrO 2 ceramics model increases.…”

Discrete element simulation model and cutting tests are conducted to investigate the surface damage during the machining of green ZrO 2 ceramics.The discrete element simulation model (DEM) is developed based on the macroscopic physical and mechanical properties of the isostatically pressed green ZrO 2 ceramics. The validity of the simulation model is verified by cutting tests on green ZrO 2 ceramics. The results show that the physical and mechanical properties of the DEM model established by the PFC2D software are consistent with the macroscopic physical and mechanical properties of the green ZrO 2 ceramics. The depth of cut, the cutting speed, and the tool rake angles have a large effect on surface/subsurface cracks. The tool rear angle has large effect on the distribution of the peak residual stresses. When the cutting force increases suddenly, the number of cracks produced increases sharply. Smaller cutting force can reduce the number of cracks and surface damage.

“…Further, Wang et al [ 15 ] discussed the effects of the cutting force on the subsurface damage of tungsten and found that the variation in the cutting force had a great influence on the number of surface defect atoms, dislocation density, and the thickness of the subsurface damage layer. Du et al [ 16 ] studied the surface quality and residual stress of alumina ceramic and zirconia ceramic after grinding under preloading stress. The surface damage of ceramics caused by abrasive grinding was reduced by using the method of preloading stress grinding.…”

The surface/subsurface damage of engineering ceramics after machining has a great influence on the service performance of parts. In order to obtain a high grinding surface quality of engineering ceramics, and take silicon nitride ceramic as a research object, a series of grinding experiments were carried out. The effects of grinding parameters on longitudinal crack propagation depth and the surface residual stress of silicon nitride ceramics were analyzed by grinding experiments, and the residual stress at the location of crack propagation was obtained. The variation in the grinding temperature under different grinding parameters was explored. The influences of the grinding temperature on crack propagation depth and surface residual stress were clarified, the distribution of residual stress along the depth direction was discussed, and the relationship between the residual stress and crack propagation was revealed. The results show that the residual compressive stress on the surface of silicon nitride ceramics decreases with the increase in the depth of crack propagation and the degree of surface brittle spalling. The residual stress at the location of the crack propagation was residual tensile stress. The crack propagation depth increased with the increase in the residual tensile stress. The research provides a reference for the realization of high-quality surfaces in the grinding of silicon nitride ceramics.
