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.
