Machining is a process in which a material (often metal) is cut to a desired final shape and size by a controlled material-removal process. The processes that have this common theme are collectively called subtractive manufacturing, in contrast to additive manufacturing, which uses controlled addition of material.Exactly what the "controlled" part of the definition implies can vary, but it ...

Early in the 18 th century, variolation (referred to then as 'inoculation') was introduced to Britain and New England to protect people likely to be at risk of infection with smallpox. This triggered a number of important developments. Among them were early examples of what we refer to today as 'evidence-based medicine' – immunization, and quantitative measures of disease severity.

The new mode of milling was much faster and therefore more economical than stone milling had been. In the roller milling process, the grain is ground into middlings, which are then sifted by hand and reground. The extensive amounts of sifting to remove the bran and the germ required a large labor force.

Milling employs rotating multi-point cutting tools to shape the workpiece. Milling tools are either horizontally or vertically oriented and include end mills, helical mills, and chamfer mills.
