  • Introduction Dimensional tolerances are selected by the designer or purchaser to make sure that the part can perform its function reliably and fit into its designed location. Assigning dimensions to a part requires identifying the desired feature size. Tolerances communicate how much variation from the desired size can be tolerated. Overly stringent tolerances are costly and do not add value. They require added work to meet tolerances that may be beyond the process capability.

  • Henry Bessemer devised a quicker, more efficient way of making steel, which led to steel replacing cast iron as the metal of preference in making railroad tracks, military weapons, and structures like bridges and skyscrapers. His invention, the Bessemer furnace, or converter, enormously raised the annual production of steel in England and helped move along the Industrial Revolution, a period of fast-paced economic change that began in Great Britain in the middle of the eighteenth century.
