The term 'Machine TOOTH' is composed of two words, 'COG' and 'TOOTH'. A COG is a wheel with teeth around its circumference that is used to transmit rotary motion from one shaft to another. The teeth of the COG are designed to mesh with other cogs or gears in order to transfer power. A TOOTH is a small, pointed projection on the surface of a gear or COG that helps it to engage with other gears or cogs. Together, the two words form the term 'Machine TOOTH', which is used to describe a component of a machine that is used to transmit power from one part of the machine to another.
