An assembly line, often called progressive assembly, is a manufacturing process where the unfinished product moves in a direct line from workstation to workstation, with parts added in sequence until the final product is completed. By mechanically moving parts to workstations and transferring the unfinished product from one workstation to ...
One of the investors they attracted was Andrew Carnegie, who saw great promise in the new steel technology after a visit to Bessemer in 1872, and saw it as a useful adjunct to his existing businesses, the Keystone Bridge Company and the Union Iron Works. Holley built the new steel mill for Carnegie, and continued to improve and refine the process.
Andrew Carnegie was born to Margaret (Morrison) Carnegie and William Carnegie in Dunfermline, Scotland, [9] in a typical weaver's cottage with only one main room. It consisted of half the ground floor, which was shared with the neighboring weaver's family. [ 10 ]
The new plant was a model of industrial efficiency for the time: it was well lit and ventilated, employed conveyors to move parts along an assembly line, and workers' stations were orderly arranged along the line. The efficiency of the assembly line allowed Ford to realize great gains in economy and productivity; in 1912, Ford sold 6,000 cars ...
Carnegie alone estimated that 40% was returned on the investment, i.e., a profit of $40,000 from a $100,000 investment in the mill. [3] The profits made by the Edgar Thomson Steel Works were substantial enough to let Carnegie and his partners, including Henry Clay Frick, his cousin George Lauder, and Henry Phipps Jr., buy
The American system of manufacturing was a set of manufacturing methods that evolved in the 19th century. [1] The two notable features were the extensive use of interchangeable parts and mechanization for production, which resulted in more efficient use of labor compared to hand methods.

Henry Ford did not invent the assembly line. He invented the *moving* assembly line in which conveyors brought the work to the operators. Interchangeable parts are parts that are sufficiently alike that any one picked from a bin, for example, can be used essentially as is. It can be put in the assembly quickly and easily and it will work.
