FiberCUT
®
ST Operation Manual
4.3 Special Case
– Starting Off the
Part
There may be times when the cut needs to
start off the edge of the part. If the
FiberCUT
®
head receives the command to
activate height sensing without a part
present, the head will reach the extended
limit and issue a crash command to the
motion system.
Implement the following sequence to
prevent this crash condition.
1. Position the head so it is located above
the part, about 10mm away from the
edge. That positioning ensures enough
surface for sensing.
2. Activate the HS1, HS2 and/or HS3 to
begin sensing on the part.
3. After the IN-POS signal actives, lock
the head by activating HOLD.
4. Move the head off the edge of the part.
5. Begin the laser processing by
activating the assist gas and turning
the beam on.
Allow at least 1 second for
pressurization.
6. Turn off HOLD shortly after the head
has moved onto the surface of the
material.
7. Continue to process as normal.
Note: It may be necessary to end the
cut in a similar method by activating
HOLD prior to moving off of the
part. Be sure to retract the head
prior to moving to the next cut
feature.
4.4 Centering the Laser through the
Tip
It is essential to any laser process to center
the beam in the gas jet tip. It is the
customer’s responsibility to center the laser
beam in the tip orifice.
4.4.1 Centering the Beam in the Tip
Orifice Manually
1. Verify that the high power beam is
disabled.
2. Put a piece of translucent tape on
the end of the gas jet tip.
3.
Turn on the laser’s internal red
pointing beam and observe the
position of the beam on the tape.
If the beam is not centered in
the tip orifice, proceed to step
4.
Do not look directly into the red
beam.
Visually locating the beam
inside the tip orifice can be
difficult. Adequate lighting and
a magnifying glass are highly
recommended.
If necessary, Laser
Mechanisms offers an
alternative solution. See
, Centering the
Beam Using the Camera
System.
