· Grinding force has a direct influence on grinding wheel wear, grinding temperature, the surface quality of the work piece and the design of machine tool component. Also, the cutting force is proportional to the specific energy in grinding and this influences the performance and surface integrity of the work piece.
· The use of small diameter media is favored because it results in a large surface area to weight ratio. Also, liner wear decreases as media diameter decreases. However, there is a limit to how small grinding media diameter can become. For one thing, smaller diameter media are more expensive per unit weight.

After completion of grinding at each section, the work piece is removed and the weight of the work piece is measured after grinding. [6, 11] VII. CYLINDRICAL GRINDING TERMINOLOGY The following terminology is used in the cylindrical grinding process as shown in Fig. 1.13.
· However, the corresponding centrifugal force would multiply by a factor of 1.167 × 1.167, or 1.36. To take a more extreme example, consider the same wheel with a maximum safe operating speed of 6,600 rpm run on a 5-inch right angle grinder at 10,000 rpm. This represents an over-speed of about 1.5 times the wheel's designed speed.
· The perfect cutting speed limits in this job are 1000 rpm, 700 rpm and 500 rpm, the feed rate is 200 mm/rev, 250 mm/rev and 300 mm/rev, and the cutting depth is 0.343684 in., 0.0011811 in. and 5 mm.
