For metal parts with tighter tolerances, interchangeability was created only for very simple parts. A pioneer here was Lieutenant General Jean-Baptiste Gribeauval (1715–1789). French artillery and artillery carriages were already standardized to five classes of cannons: 4, 8, 12, 16, and 24 pounders.
Did you know that Eli Whitney made guns with interchangeable parts?
This I had not known, but apparently it is old news: The symbolic kingpin of interchangeable parts production fell in 1960 when Robert S. Woodbury published his essay “The Legend of Eli Whitney and Interchangeable Parts”…Woodbury convincingly argued that the parts of Whitney’s guns were not in fact constructed with interchangeable parts…
What was the purpose of interchangeable parts in firearms?
The use of interchangeable parts removed the problems of earlier eras concerning the difficulty or impossibility of producing new parts for old equipment. If one firearm part failed, another could be ordered, and the firearm would not need to be discarded. The catch was that Whitney's guns were costly and handmade by skilled workmen.

Who came up with the idea of interchangeable parts?

How many rifles did Eli Whitney buy?
Eli Whitney bought ten rifles in front of the Congress and unassembled all of them. He then reassembled the rifles but used the components of different rifles and even then, the rifles worked perfectly. The idea of assembling the weapons was not intimidating enough however, the idea of Interchangeable Parts caught the attention of everyone.
What is Eli Whitney's most famous invention?
Born on December 2, 1765, Eli Whitney was an American inventor, who is best known for his invention of Cotton Gin, which turned the production of the cotton crop into a profitable business. Other well-known inventions by Eli Whitney include Interchangeable Parts and Milling Machine. Despite these great inventions, Whitney lost several profits in legal battles over the patent for Cotton Gin. However, he secured contracts with the United States Army for the manufacturing of muskets until his death on January 8, 1825. In 1978, he secured a contract to assemble 10,000 muskets and manufactured them in a record time of 2 years.
Where did the use of interchangeable parts come from?
Evidence of the use of interchangeable parts can be traced back over two thousand years to Carthage in the First Punic War. Carthaginian ships had standardized, interchangeable parts that even came with assembly instructions akin to "tab A into slot B" marked on them.
What is interchangeable parts?
Components that are identical for practical purposes. Interchangeable parts are parts ( components) that are, for practical purposes, identical. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, ...
What is interchangeability in assembly?
Interchangeability relies on parts' dimensions falling within the tolerance range. The most common mode of assembly is to design and manufacture such that , as long as each part that reaches assembly is within tolerance, the mating of parts can be totally random. This has value for all the reasons already discussed earlier.
What is selective assembly?
In either case the principle of selective assembly is the same: parts are selected for mating, rather than being mated at random . As the parts are inspected, they are graded out into separate bins based on what end of the range they fall in (or violate). Falling within the high or low end of a range is usually called being heavy or light; violating the high or low end of a range is usually called being oversize or undersize. Examples are given below.

Mass production using interchangeable parts was first achieved in 1803 by Marc Isambard Brunel in cooperation with Henry Maudslay and Simon Goodrich, under the management of (and with contributions by) Brigadier-General Sir Samuel Bentham, the Inspector General of Naval Works at Portsmouth Block Mills, Portsmouth Dockyard, Hampshire, England. At the time, the Napoleonic War was at its height, and the Royal Navy was in a state of expansion that required 100,000 pulley blocks to be manufactured a year. Bentham had already achieved remarkable efficiency at the docks by introducing power-driven machinery and reorganising the dockyard system.
When was the American system of manufacturing invented?
Methods for industrial production of interchangeable parts in the United States were first developed in the nineteenth century. The term American system of manufacturing was sometimes applied to them at the time, in distinction from earlier methods. Within a few decades such methods were in use in various countries, so American system is now a term of historical reference rather than current industrial nomenclature.

Overview
Implementation
Numerous inventors began to try to implement the principle Blanc had described. The development of the machine tools and manufacturing practices required would be a great expense to the U.S. Ordnance Department, and for some years while trying to achieve interchangeability, the firearms produced cost more to manufacture. By 1853, there was evidence that interchangeable …
First use
Evidence of the use of interchangeable parts can be traced back over two thousand years to Carthage in the First Punic War. Carthaginian ships had standardized, interchangeable parts that even came with assembly instructions akin to "tab A into slot B" marked on them.
In East Asia, during the Warring States period and later the Qin Dynasty, bronze crossbow triggers and locking mechanisms were mass-produced and made to be interchangeable.
Origins of the modern concept
In the late 18th century, French General Jean-Baptiste Vaquette de Gribeauval promoted standardized weapons in what became known as the Système Gribeauval after it was issued as a royal order in 1765. (Its focus at the time was artillery more than muskets or handguns.) One of the accomplishments of the system was that solid cast cannons were bored to precise tolerances, which allowed the walls to be thinner than cannons poured with hollow cores. However, becaus…
Socioeconomic context
The principle of interchangeable parts flourished and developed throughout the 19th century, and led to mass production in many industries. It was based on the use of templates and other jigs and fixtures, applied by semi-skilled labor using machine tools to augment (and later largely replace) the traditional hand tools. Throughout this century there was much development work to be done in creating gauges, measuring tools (such as calipers and micrometers), standards (such as thos…
