PROGRAMMING18. SPECIFYING THE LASER FUNCTION
The high–speed laser machining function offers the following functions:
(2)Beam on/off control in the RISC mode
(3)Beam output condition delay control
(4)Power control function
(5)Parameter switch function for high–speed machining
This function can be used only for a two–dimensional command. If this
function is used for a three–dimensional command, no alarm is generated,
but this function does not operate normally.
This function is optional.
To execute successive miniature blocks accurately at high speed, the
following functions are implemented:
(1)Multi–block look–ahead acceleration/deceleration function before
(2)Automatic feedrate control function
For details, refer to the Operator’s Manual (B–63534EN) provided with
the FANUC Series 160i/160i–MB.
The beam output condition can be changed by specifying S, P, Q, and E
in RISC mode.
(1)In the same way as in the normal mode, specify S (peak power), P
(pulse frequency), Q (pulse duty cycle), and E (machining condition
number) in a block specifying G01 (G02 or G03).
(2)An E code can be specified singly. The machine decelerates in the
(3)The Q command is used to turn the beam on or off in RISC mode. To
turn the beam on, specify Q = 1 to 100. To turn the beam off, specify
Q = 0.
(4)In RISC mode, the tracing control commands (G13, G14), assist gas
control command (G32), piercing command (G24), and power control
command (G63) cannot be specified. These commands must be
specified before setting RISC mode or after canceling RISC mode.
To compensate for the delay between machine operation and beam on/off
operation, beam output is delayed for a parameter–set delay from the start
of the block.
(1)A delay of 0 to 64 ms, in units of 8 ms, can be set using a dedicated
(2)This function can be enabled or disabled by a parameter.
(3)This function is enabled in RISC mode.
In beam output condition delay control mode, output condition
modifications can be made only by using the S, P, Q, and E codes in the
program. Output condition modifications cannot be made by using the
