Glossary of Terms

Assemblies
the putting together of complex machinery, as airplanes, from interchangeable parts of standard dimensions.
Batch Production
production is a technique used in manufacturing, in which the object in question is created stage by stage over a series of workstations. With job production and flow production it is one of the three main production methods
CNC Milling
CNC is short for Computer Numerical Control -it refers to a computer "controller" that reads instructions and drives the machine tool. CNC's are able to perform precision cuts reliably in machine shop settings. Most machine shops would have CNC lathes, CNC routers, CNC milling machines, etc.
CNC Turning
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical toolpath by moving more or less linearly while the workpiece rotates. The tool's axes of movement may be literally a straight line, or they may be along some set of curves or angles, but they are essentially linear (in the nonmathematical sense). Usually the term "turning" is reserved for the generation of external surfaces by this cutting action, whereas this same essential cutting action when applied to internal surfaces (that is, holes, of one kind or another) is called "boring". Thus the phrase "turning and boring" categorizes the larger family of (essentially similar) processes. The cutting of faces on the workpiece (that is, surfaces perpendicular to its rotating axis), whether with a turning or boring tool, is called "facing", and may be lumped into either category as a subset.
