The process for the creation of cotton into clothing is a simple one that all beings with the wondrous cotton plant. The cotton ball that the plant produces is the end result of the flower of the cotton plant. Once the flower dies and falls off, all that is left are the cotton bolls and the seeds. This is what is harvested around the world.

DESCRIPTION
Milling cutters are cutting tools typically used in milling machines or machining centres (and occasionally in other machine tools). They remove material by their movement within the machine (, a ball nose mill) or directly from the cutter's shape (, a form tool such as a hobbing cutter).

Lathe – ball-turning, spherical surfaces, concave and convex. A common problem on the lathe is turning convex and concave surfaces. A particular case of this is turning a ball. But, usually, it is not a complete ball that is required but a ball on the end of a shaft. Among the possible methods are: using one or more form tools,

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
