How machines learned precision
This article explores the historical evolution of precision engineering during the Industrial Revolution, focusing on the development of lathes and measurement tools. It traces how advancements in machining allowed for the creation of accurate steam engine components.
Why it matters
Understanding the history of precision manufacturing provides context for modern industrial standards and technological progress.
Accuracy from Iron in the Industrial Revolution
This is a screw-cutting lathe of the kind Henry Maudslay built in London around 1800. A labourer turns the large wheel to spin the bar in the middle, and a cutting tool moves along beside it on a carriage that slides on straight iron rails. A long screw moves the carriage the same distance on every turn of the bar, cutting a thread into its surface. Lathes like this made shafts and screws for steam engines, looms, locomotives and other lathes.
