"For a machine to run smoothly and predictably, its parts must be standard and hence replaceable."
–Charles Eisenstein
"Many of us take better care of our automobiles than we do of our own bodies . . . yet the auto has replaceable parts."
–B.J. Palmer

The use of interchangeable parts is really just the next logical step in the process of integrating the economy with the technological development. It makes much more sense to make machines which use standardized parts, which could be produced separately, and used later to replace broken sectors of the machine without having to rebuild everything from scratch, then for example, to produce \n item so that - once broken - it has to be replaced for a brand new item of the same kind (hugh).

Wide use of replaceable parts will later find its place in all production cycles. It immediate benefits are, however, already considerable: thanks to it, new, inexpensive modern guns and munitions for these guns can be supplied freely to form the next-generation modern foot soldier - the Infantry. Thanks to it again, farming can now use machines for its everyday deeds, such as irrigation, sowing and harvesting, for a vast improvement of food production.

Historical Context Edit

Evidence for the use of interchangeable parts can be traced back to the warships of Carthage during the First Punic War, when standardized parts made repairs to their galleys relatively quick. During the Warring States period, the Qin dynasty employed mass-produced crossbows with interchangeable parts to pummel its rivals. So it was throughout the ages, until Eli Terry finally mass made something not a weapon on his production line in America in 1814 AD – a pillar-and-scroll clock. In the mid-1800s, several clock and sewing machine manufacturers started using interchangeable parts in their factories. Both the Singer Sewing Machine Corporation (1870) and McCormick Harvesting Machine Company (1880) adopted the practice, followed by steam engine, typewriter and bicycle manufacturers. And then Henry Ford adopted it for his affordable brand of automobiles.

The development of interchangeable parts in manufacturing was due in large part to the innovation and invention of a number of manufacturing machines, which permitted only very small variances in the final parts. Manufacturing was revolutionized by the slide rest lathe, screw cutting lathe, milling machine and metal planer, in turn. Add electrification of the machines for higher speed, and now hundreds of identical parts could be churned out each hour by skilled machinists. Configuration management evolved in the 1950s as a systems engineering field to insure consistency in performance and physical attributes of manufactured parts. Then came robots to work the assembly lines.

The development of replaceable parts in all realms of consumer products spurred the Industrial Revolution, and boosted the quality of life since all kinds of things became affordable to the average working-class person. Conspicuous consumption was at last within the reach of civilization … or at least, of some of it.
