G-Code
G-code is one of a number of computer code languages that
are used to instruct CNC machining devices what motions they
need to perform such as work coordinates, canned cycles, and
multiple repetitive cycles. G-Code is the most popular programming
language used for programming CNC machinery. See CNC
and CNC Controlled.

Gas Jet
Gas which is blown into the cut to clear away molten metals,
or other materials in the cutting zone. In some cases, the
gas jet can be chosen to react chemically with the workpiece
to produce heat and accelerate the cutting speed.
Gas Jet
Assist
An assisting coaxial gas, often oxygen, argon, or nitrogen,
that may be used to achieve very high power levels needed
for cutting certain metals.
Gas Laser
A type of laser in which the laser action takes place in
a gas medium.
Gas Mix
CO2 lasers use a mixture of carbon dioxide, helium, and nitrogen.
Most applications can be done using a standard, predetermined
ratio of these gases. Some applications require pulses with
high peak energy and rapid decay of the pulse tail. Increasing
the volume of CO2 gives this result. Increasing the volume
of nitrogen allows operation of a laser at lower than its
normal minimum CW power
level.
Gas Pressure
The pressure of the Assist
Gas that is usually measured in pounds per square inch
(psi). With oxygen, gas pressure can range from 15 to 50 psi.
With inert gases, the gas pressure can range from 30 to 200
psi.
Glasses
Most glasses are not laser cut. They have a high absorptivity
to CO2 laser light and demonstrate cracking along the edge
cut due to the rapid thermal cycle associated with laser cutting.
However, a laser can effectively cut quartz and heat resistant
glasses.
