2. Threading (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Threading_(manufacturing)

   In manufacturing, threading is the process of creating a screw thread.More screw threads are produced each year than any other machine element. [1] There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such as ...

   Henry Maudslay's early screw-cutting lathes of circa 1797 and 1800.. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
