Eli Terry was using interchangeable parts using a milling machine as early as 1800. Ward Francillon, a horologist, concluded in a study that Terry had already accomplished interchangeable parts as early as 1800. The study examined several of Terry's clocks produced between 1800–1807. The parts were labelled and interchanged as needed.
EasyEDA is a web-based electronic design automation (EDA) tool suite that enables hardware engineers to design, simulate, share (publicly and privately) and discuss schematics, simulations and printed circuit boards, and to create a bill of materials, Gerber files, pick and place files and documentary outputs in the file formats PDF, PNG, and SVG.
Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
Like his contemporary Simeon North, Hall began using this mill power to run machine tools and achieve the dimension controls necessary for interchangeable parts. He employed metal-cutting machines attached with cutters and saws in the place of the standard heavy labor, made from cast-iron frames to ensure structural integrity and minimize ...
According to Muir's book Reflections in Bullough's Pond, North "was the first arms maker to implement a number of machine production techniques, yet he cautiously halted his pursuit of mass-produced, interchangeable parts" whenever it became apparent that it was uneconomic. For some time, interchangeable-part manufacturing in metal continued to ...

Having won the contract, they then constructed a four-story brick building beside Mill Brook. Over the next eight years, the factory was built and machines to make precision parts were made. They brought in workers and mechanics, invented new machines, adapted old ones, and perfected techniques for producing interchangeable parts.
