Investigation on the removal characteristics of single-point cutting high-volume fraction SiCp/Al composites

SiC-reinforced aluminum matrix composites (SiCp/Al composites) are typically difficult-to-machine material, and the irregular SiC diffused in SiCp/Al make surface quality worse. In this paper, a single-point cutting simulation with variable plane depth were conducted for composite higher volume fraction (65 Vol%) alloy. The morphology characteristics of composites, which mainly include breaking, part pulling out, protruding, al tearing, interface debonding, different from those alloy materials. high-volume lower profile dimensional accuracy composites. There thin discrete layers covered on machined surface. Finally, test, meets actual grinding condition, was 2A12 alloy, 45% composite, 65% composite. results verified by experimental data obtained test.
