Some observations in grinding SiC and silicon carbide

May 10, 2019 Because of low thermal conductivity and high mechanical strength, silicon carbide (SiC) ceramics are widely used in valves, pistons, bearing, etc. [1,2,3,4].But cracks and collapse are easily observed in the process of machining [5,6,7].To achieve the ideal machining surface quality, grinding with a diamond grinding wheel is often expropriated.

Residual Stress Distribution in Silicon Wafers Machined by

May 10, 2017 Subsurface damage (SSD) and grinding damage-induced stress (GDIS) are a focus of attention in the study of grinding mechanisms. Our previous study proposed a load identification method and analyzed the GDIS in a silicon wafer ground (Zhou et al., 2016, “A Load Identification Method for the GDIS Distribution in Silicon Wafers,” Int. J. Mach. Tools Manuf., 107, pp. 1–7.).
