All the grinding grains in contact with the workpiece create a machining pattern by means of overlaying individual sinusoidal lines that cross each other at a particular angle. This generates a specific, defined pattern of grooves and plateaux, which, in turn, results in the particular advantages of the superfinishing process.

Grinding or finishing at an angle that is too steep may cause you to work much harder than necessary since you're not getting the full benefit the product is designed to provide. When using cutting wheels, hold the tool at a 90-degree angle, perpendicular to the workpiece. This position enhances safety and helps improve wheel life and cut rate.

"Creep-feed grinding is a process that can deliver more than you realize," Wiss says. With creep-feed grinding, manufacturers can take larger depths of cut than they can with traditional surface grinding. Even added to a slow traverse rate, the material removal rate (MRR) that can be achieved is much higher than that of finish grinding.

2.1: Grinding Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used.
