A theoretical assessment of surface defect machining and hot machining of nanocrystalline silicon carbide

In this paper, a newly proposed machining method named "surface defect machining" (SDM) was explored for machining of nanocrystalline beta silicon carbide (3C-SiC) at 300 K using MD simulation. The results were compared with isothermal high temperature machining at 1200 K under the same machining parameters, emulating ductile mode micro laser assisted machining (μ-LAM) and with conventional cutting at 300 K. In the SDM simulation, surface defects were generated on the top of the (010) surface of the 3C-SiC work piece prior to cutting, and the workpiece was then cut along the âŒ
