In bonded abrasive processes, the particles are held together within a matrix, and their combined shape determines the geometry of the finished workpiece. For example, in grinding the particles are bonded together in a wheel. As the grinding wheel is fed into the part, its shape is transferred onto the workpiece. abrasive machining processes - IIT Kanpur,For certain abrasive processes, dimensions can be held to extremely close tolerances.
