Eli Whitney received a contract from the US Army to produce muskets having interchangeable parts. He fulfilled the contract to the satisfaction of the US Army at that time, delivering the requested quantity of muskets.
However in the 1980s several samples of still existing muskets produced under this contract were carefully examined. It was found that they actually had no interchangeable parts, each musket was unique just like those made by other gunmakers of the day!
It is believed that Eli Whitney encountered problems with the tooling he had built to make the various parts interchangable and in order to meet the delivery deadlines of the contract just "filed" the parts as needed to make them fit the gun they went into.
On other projects where Eli Whitney was under less time pressure he may have succeeded in making interchangeable parts.
Eli Whitney's interchangeable parts made factory assembly lines possible.
