Abstract
This research project presents quantitative informa¬tion about surface grinding. Part one investigates tool life. Part two quantitatively studies the effect of sparkout on surface finish. Part three identifies the individual as well as the combined effects of different factors on surface finish and power requirements.
Grinding, as applied to the machining processes, de¬scribes the removal of metal by means of rotating abra¬sive wheels. It is a metal cutting process similar in many ways to other commonly employed methods of metal re¬moval such as milling, turning and shaping. In fact, a grainding wheel may be described as a multi-toothed mill¬ing cutter, each tooth consisting of a small abrasive

On the other hand, there are many fundamental differ¬ences between the grinding process and the other machining methods. In most metal cutting processes, the tools have known geometry and orientation, but in grinding there are randomly oriented cutting teeth. In most grinding pro¬cesses, depths of cut taken by the abrasive grains are very small compared with cuts taken in other machining
