What do you want to know? Basically, cell manufacturing is a 'theory' that if machines are grouped in a "work cell" so that all the processes can be done with minimal movement of the parts and operators then you will be more effecient. Remember in the old days when all the lathes were grouped together on one side of the shop and the mills on the other side? Bridgeports all in a line and drill presses stacked in neat rows. In a "cell" you might have a machining center, a lathe, a Bridgeport and a drill press all in a "U" shaped configuration so that a part can be run from start to finish.
