PROGRAMMING 18. SPECIFYING THE LASER FUNCTION
B–63664EN/02
339
The laser power control function ensures uniform machining by
controlling the peak power, pulse frequency, and pulse duty when the
actual feedrate changes from that specified for corners and other
locations.
G63 P1; Laser power control mode
G63 P0; Laser power control mode cancel
NOTE
G63 must be specified independently. (Do not specify other
G codes in the block.)
The laser power control function controls the power specification, pulse
frequency, and pulse duty, using the formula shown below:
M + Mo ) (Mc–Mo)
F
Fc
Mo : Power, frequency, or duty at a feedrate (F) of 0.
Set with a parameter.
Mmin : Minimum clamp value for the power, frequency, or duty (parameter).
Set with a parameter.
Mc : Power, frequency, or duty specified when laser power control
mode is ON.
Set with a program.
Fc : Feedrate specified when laser power control mode is ON.
Set with a program.
