The moving assembly line appeared to the onlooker to be an endless contraption of chains and links that allowed Model T parts to swim through the sea of the assembly process. In total, the manufacturing of the car could be broken down into 84 steps. The key to the process, however, was having interchangeable parts.

Thus the main wear parts in these mills are the balls themselves, and the liners. The balls are simply "consumed" by the wear process and must be restocked, whereas the liners must be periodically replaced. The ball and tube mills are lowspeed machines that grind the coal with steel balls in a rotating horizontal cylinder.

In this work, we examine certain modeling and control aspects associated with the assembly of flexible payloads with a multirobot system. While this particular problem is of a general nature, our work is motivated by the particular problem presented by the assembly of automotive bodies from sheet metal parts.

understanding journal bearings and is integral to bearing design and application. ... The primary advantage of a fluid film bearing is often thought of as the lack of contact between rotating parts and thus, infinite life. In a pure sense, this is true, but other complications make this a secondary reason for using these bearings. ...
