Abstract：In-situ TiB2/Al composites have extensive application prospect in the field of aeronautics and astronautics
due to their outstanding mechanical properties, such as low density, high specific strength and high specific modulus. Grinding
experiments were conducted to analyze the grinding performance of in-situ TiB2/Al composites in different grinding parameters
by using single alumina wheel, white alumina wheel, and cubic boron nitride wheel respectively. The influence of
grinding wheel, wheel speed, workpiece speed, and depth of cut on surface roughness were investigated. Moreover, the topography
of grinding surface, grinding chips, and the wear on grinding wheel were observed to analyze the surface forming
mechanism of in-situ TiB2/Al composites. Finally, the optimal grinding parameters were selected based on the experimental
date. The research contents and conclusions will provide theory support for in-situ TiB2/Al composite grinding process.
