The Emergency Stop is usually a button that you press to
stop the machine in the event of an emergency.
Edge Factor/Edge Deformation
Laser cut parts exhibit little no edge factor, roll-off,
or edge deformation.
The condition of the cut edge. High edge quality is strongly
promoted by good control of the laser beam and by a stable
Acronym for Electrical Discharge Machining. A slow, but extremely
precise method of machining using electrical discharge to
remove material in very small increments. Laser cutting has
replaced many EDM applications.
The product of power (watts) and duration (seconds). One
watt second = one Joule.
A laser with an assigned class number higher than the inherent
capability of the laser system in which it is incorporated,
where the system's lower classification is appropriate to
the engineering features limiting accessible emission. See
Enclosed Laser Device.
Any laser or laser system located within an enclosure which
does not permit hazardous optical radiation emission from
the enclosure. The laser inside is termed an "embedded
laser." See Embedded Laser.
Marking the material without cutting all the way through.
This is typically accomplished by reducing power.
