The term "LASER" is an acronym for
Light
Amplification by
Stimulated
Emission of
Radiation.
How laser cutting works.
- Laser cutting works by
directing the output of a high power
laser at the material to be cut. The
material then either melts, burns or
evaporates away leaving a cutting
edge.
Minimum Distance between objects
ready for laser cutting.
As a guide: The thicker the material
to be laser cut the wide the free
space should be between letters,
object and shapes or other lines or
spacers.
- Set a minimum
8mm for All
objects and lettering,
regardless of size or thickness,
grade of materials to be laser
cut or other when you are making
signs and signage.
Cutting Techniques
One of the many advantages of
fabricating with a laser is the
ability to engrave and cut in the
same job. When creating jobs for
laser cutting in your layout
program, you must first understand
that the difference between a raster
and vector line is the thickness of
line. Most laser systems view a line
thickness that is .01mm. or less as
a vector line. See our Ezine on
Vector drawing and Bitmap
Comparisons.
Advantages of laser cutting over
mechanical cutting such as router
cut signs or saw cut signage vary
according to the situation, but
important factors are; lack of
physical contact, since there is no
cutting edge which can become
contaminated by the material or
contaminate the material, and to
some extent precision, since there
is no wear on the laser.
Disadvantages of laser cutting may
include the high energy required.
What is laser cutting?
Capabilities that
providers of laser machining
services offer include size
and capacity considerations
and materials processed.
Size and capacity choices
include micro machining,
less than 5mm. Micro
machining is precision
machining of integrate
detail on small parts.
Materials processed by
providers of laser machining
services include exotic
metals and alloys, ferrous
metals, nonferrous metals,
precious metals, glass or
ceramics, plastics, rubber,
sapphire or quartz, and
stone or marble or granite.
Industrial laser cutting is
a CNC controlled,
non-contact cutting tool
process that allows quick,
accurate cutting with a
narrow kerf (cutting
groove). Laser types for CNC
laser cutting include CO2
lasers. Laser cutting is a
very versatile operation
that has short setup times,
and can be used to cut a
wide range of materials of
varying hardness and
composition. Some of the
advantages of laser cutting
are high accuracy, cutting
of unlimited and complex
shapes, clean cutting that
requires little or no
finishing and generates a
minimum amount of heat, and
distortion-free cutting.
Laser cutting can be used
with a wide range of
materials. In addition to
stock metals, stone,
plastics and rubbers, laser
cutters are often used on
exotic metals and minerals
that would quickly dull or
damage conventional blade or
wire cutters. These included
such items as hardened
ceramics and precious
gemstones.
In addition to straight
laser cutting, many laser
cutting job shops can
provide a wide range of
custom laser cutting
services. Some of these
include laser cutting and
stencilling, laser cutting
drilling, and laser welding.
While similar to laser
cutting, these secondary
operations involve more
intricate or precise marking
abilities. Generally, the
laser types used are the
same as straightforward
laser cutting.
