Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process.

The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.

Exactly what the "controlled" part of the definition implies can vary, but it almost always implies the use of machine tools (in addition to just power tools and hand tools).

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways.

Valves are technically fittings, but are usually discussed as a separate category.

In an open valve, fluid flows in a direction from higher pressure to lower pressure.

The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll.

Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks.

It is also commonly referred to as train transport.

In contrast to road transport, where vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run.

Tracks usually consist of steel rails, installed on ties (sleepers) and ballast, on which the rolling stock, usually fitted with metal wheels, moves.

Other variations are also possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface.
