|
◆ Knowledge
Introduction |
| |
Laser marking is using
appropriate energy
density, focused laser
beam on the surface of
the workpiece to scan
the target surface, the
material physical or
chemical changes in the
formation of traces on
the surface, thus
forming the marking
process. It belongs to a
non-contact marking
method. Compared with
the traditional
processing methods, it
has the advantages of
wide application range,
fast marking speed,
stable performance, high
quality, low running
cost, little
environmental pollution,
easy computer control
and synchronous
operation with other
equipments. Therefore,
the laser marking has
become one of the
important applications
of laser.
Through the study of this experiment, students can understand
the principle of laser
generation and marking,
also the components of
marking machine and the
fiber laser in different
samples on the marking
process test rules, the
experimental results
were also discussed. |
