Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.

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.
