In modern CNC systems, end-to-end component
design is highly automated using computer-aided design (CAD) and computer-aided
manufacturing (CAM) programs. The programs produce a computer file that is
interpreted to extract the commands needed to operate a particular machine by
use of a post processor, and then loaded into the CNC machines for production.
Since any particular component might require the use of a number of different
tools – drills, saws, etc. – modern machines often combine multiple tools into
a single "cell". In other installations, a number of different
machines are used with an external controller and human or robotic operators
that move the component from machine to machine. In either case, the series of
steps needed to produce any part is highly automated and produces a part that
closely matches the original CAD design
Brass is a metal alloy made of copper and
zinc; the proportions of zinc and copper can be varied to create a range of
brasses with varying properties. It is a substitutional alloy: atoms of the two
constituents may replace each other within the same crystal structure.
By comparison, bronze is principally an
alloy of copper and tin. However, bronze and brass may also include small
proportions of a range of other elements including arsenic, phosphorus,
aluminum, manganese, and silicon. The term is also applied to a variety of
brasses, and the distinction is largely historical. Modern practice in museums
and archaeology increasingly avoids both terms for historical objects in favour
of the all-embracing "copper alloy".
Brass is used for decoration for its bright
gold-like appearance; for applications where low friction is required such as
locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing
and electrical applications; and extensively in brass musical instruments such
as horns and bells where a combination of high workability (historically with
hand tools) and durability is desired. It is also used in zippers. Brass is
often used in situations in which it is important that sparks not be struck,
such as in fittings and tools used near flammable or explosive materials
