2015-1-1  The grinding process is most easily understood with reference to the abrasive grits (hard particles with sharp edges) bonded into a wheel which rotates with a high speed. The orientation of individual grains is random; therefore, a grain may encounter the workpiece surface with a positive, zero, or, as is most likely, with a negative rake angle ( Figure 3.1 ).

Grinding Machining Process : Complete Notes

2018-12-23  In the grinding process, a layer of abrasive is responsible for removing the material from the work piece. As machining starts, the abrasives of grinding wheel and work piece comes into contact and due to the rubbing force the initial layer from the grinding wheel is worn out and a fresh layer of the abrasives involve in machining this process is continuously repeated until complete machining is done.
