module is impossible.
Given the evidence mentioned above, it is furthermore worth sug-
gesting that there was an aftermath to applying the modular design to
the manufacturing line in the beginning of the 1960s. Actually, the man-
ufacturing line consisting of different kinds of the machine was used on
work to aim at the enhancement of economic benefit. For example, the
Cincinnati Milling Machine merchandised a manufacturing line for pro-
cessing the piston rod with 0.0001 in for roundness, 0.0002 in for
straightness, ±0.0002 in for size, and so on. The line consisted of five
