Effect of grinding depths on SiC nanogrinding behavior ...
The effect of grinding depth on nanogrinding of single-crystal 3C-SiC is studied by molecular dynamics. With the assistance of the software Ovito, the atomic displacement, radial distribution function, amorphous atoms, dislocation, force and von Mises stress distribution and abrasive wear are analyzed, and we get the following conclusion: 1 ...

Grinding Machining Process : Complete Notes - mech4study
The self-sharpening behaviour of grinding wheel is a necessary part of the grinding machine and the selection of the grinding wheel depends on the work material. The bond between the abrasives is not too strong if the bonds retain the abrasives strongly then it will not allow the abrasive to be pulled out after wear.
