As the grinding process continues the grinding wheel wear and loading changes the texture of the grinding wheel surface which changes the reflective characteristics of the grinding wheel surface

Topography change of the grinding wheel during grinding process grinding fluid which causes the difficulty of the inprocess measurement is often used to cool a workpiece some inprocess measurement methods of wear of a grinding wheel have been proposed for both dry and wet grinding 12 some methods to detect or measure loading dulling

The grinding forces force ratio and grinding temperatures decreased with the increasing proportions of whole crystal and the decreasing mean protrusion height of diamond grits and the tangential and normal force components increased with the gradual wear of the brazed diamond wheel during a longtime grinding process

Process of conditioning worn grains on the surface of a grinding wheel by producing sharp new edges on grains so they cut more effectively and truing the grinding wheel so its profile is once again truly circular this is often done using a cnc diamondpoint tool or starshaped steel disks

To gain a better understanding of the wear process grinding forces were measured using a computerbased dataacquisition system stylus profilometry served to measure the volumetric wheel wear and to measure the surface roughness of the ground silicon nitride for the purpose of characterizing the effect of wheel wear on the grinding performance
