The sp3-to-sp2 transition and consequent wear of a diamond tool during single-point diamond turning of cubic SiC.

Work by Saurav Goel and Xichun Luo (Heriot-Watt University) to simulate single-point diamond turning (SPDT) of cubic SiC, as an application of ultra-precision machining. This work includes an MD model for quantification of wear of diamond tools involving graphitization.

The figure shows the sp3-to-sp2 transition and consequent wear of a diamond tool during SPDT of cubic SiC.
