Molecular dynamics simulation model for the quantitative assessment of tool wear during single point diamond turning of cubic silicon carbide

► A three body potential function is proposed to simulate SPDT of SiC precisely. ► Diamond undergoes sp3-sp2 transition which happens to be the cause of tool wear. ► Radial distribution function can characterize the graphitization of diamond. ► Change in coordination number can be used to quantify the diamond tool wear.
