PROGRAMMING 18. SPECIFYING THE LASER FUNCTION
When assist gas switching is performed for piercing in edge machining,
whether to output a beam for the assist gas settling time can be specified
by setting bit 4 of parameter No. 15004.
When assist gas switching is not to be performed for edge machining, set
the assist gas selection value to 0 or the same value as for machining. If
0 is set as the assist gas selection value for edge machining, the assist gas
selection value for machining is used.
In assist gas switching performed at the start of piercing in edge
machining, at the start of the subsequent return distance cutting, and at the
start of startup machining, when the gas type and gas pressure defined
with a specified edge selection number and startup selection number are
the same as those for cutting, set bit 3 of parameter No. 15011 to 1 if the
set assist gas settling time is to be ignored.
When the assist gas output conditions defined with a specified edge
selection number or a startup selection number are to be used as the assist
gas output conditions for return distance cutting in edge machining and
startup machining, set bit 0 of parameter No. 15011 to 1.
If bit 0 of parameter No. 15011 and bit 3 of parameter No. 15011 are set
at the same time, the setting of bit 0 of parameter No. 15011 is assumed.
The setting of bit 3 is ignored.
When assist gas is switched for edge machining, whether to stop beam
output during the assist gas settling time can be specified.
#6 #5 #4
#3 #2 #1 #0
0 : Stops beam output when assist gas is switched for edge machining.
1 : Does not stop beam output when assist gas is switched for edge
2) Nonselection of assist gas
When assist gas selection is not required for edge machining, specify
0 or the same value as that used for machining for the assist gas
selection on the edge machining condition setting screen.
With this setting, the execution of a settling time for assist gas
switching can be ignored.
The normal override function can be used for the following settings used
to perform edge machining:
S Return feedrate
S Return frequency
S Return duty cycle
As the reference displacement value and gap value for gap control in edge
machining, values set in the edge machining conditions are used. If a set
value is 0, the value set for machining becomes effective.
