Thomas Blanchard (June 24, 1788 – April 16, 1864) was an American inventor who lived much of his life in Springfield, Massachusetts, where in 1819, he pioneered the assembly line style of mass production in America, and also invented the first machining lathe for interchangeable parts. Blanchard worked, for much of his career, with the ...
The Hermitage Museum, Russia, displays the Nartov's copying lathe used for ornamental turning: making medals and guilloche patterns designed by Nartov in 1721. [2] Nartov's lathe duplicated the pattern from a template to a blank, cutting to the preset scale. A probe traced the template and the cutter cut accordingly.
Thomas Blanchard built his gun-copying lathes (1820s–30s), and the work of people such as Christopher Miner Spencer developed the turret lathe into the screw machine (1870s). Cam-based automation had already reached a highly advanced state by World War I (1910s).
1822: Thomas Blanchard invents the pattern-tracing lathe (actually more like a shaper). The lathe can copy symmetrical shapes and is used for making gun stocks, and later, ax handles. [412] [413] 1822: Nicéphore Niépce invents Heliography, the first photographic process.
Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
Multiaxis machining is a manufacturing process that involves tools that move in 4 or more directions and are used to manufacture parts out of metal or other materials by milling away excess material, by water jet cutting or by laser cutting. This type of machining was originally performed mechanically on large complex machines.
Another important innovator is Thomas Blanchard, who in 1819 invented the Blanchard lathe, which could produce identical copies of wooden gun stocks. [33] Interchangeable parts made the development of the assembly line possible. In addition to making production faster, the assembly line eliminated the need for skilled craftsmen because each ...
In 1819, Thomas Blanchard created a lathe that could reliably cut irregular shapes, like those needed for arms manufacture. By 1822, Captain John H. Hall had developed a system using machine tools , division of labor, and an unskilled workforce to produce a breech-loading rifle —a process that came to be known as " Armory practice " in the U ...
