Abrasive processes, which are mostly applied for achieving high accuracy and high quality of mechanical, electrical, and optical parts, can be divided into two categories, fixed abrasive processes and loose abrasive processes. In fixed abrasive processes, grinding wheels or honing stones are used as tools and the abrasives are held together with bonding material, also providing sufficient pores for chip removal. In loose abrasive processes, the individual grains are not fixed and are usually sup
