19. HIGH SPEED CUTTING FUNCTIONS
511
If an F command is used in a G05.1 Q1 (AICC or AI nanoCC) block or
G05 P10000 (AI–HPCC or AI–nanoHPCC) block, the speed specified
with the F command is assumed the acceleration/deceleration reference
speed.
This acceleration/deceleration reference speed is cleared upon a reset.
After the acceleration/deceleration reference speed is cleared upon a reset
or after the power is turned off and then on again, the
acceleration/deceleration reference speed specified for parameter No.
7066 (AICC or AI nanoCC) or No.19520 (AI–HPCC or AI–nanoHPCC)
will be used. (Method (2), described later)
If the acceleration/deceleration reference speed specified for the
parameter is 0, the feedrate assumed at the start of cutting will be assumed
the acceleration/deceleration reference speed. (Method (3), described
later)
(Program example)
G05.1 Q1 F5000 ; ··· Sets the reference speed to 5000 mm/min.
The F command used in a G05.1 block is used to
specify the acceleration/deceleration reference speed,
and is also used as a normal F command.
Even if the feedrate is changed during the execution of the machining
program, the acceleration/deceleration reference speed specified with the
above command remains in effect. If this occurs, the machining time may
become longer because machining is performed at the feedrate different
from the acceleration/deceleration reference speed.
For this reason, the acceleration/deceleration reference speed to be
specified with the above command should be as close as possible to the
actual machining speed.
NOTE
The G05.1Q1Fxxxx, G05P10000Fxxxx command must be
issued in feed per minute (G94) mode.
If this command is issued in another mode, the speed
specified with this command will be generated the alarm
(PS5111).
the acceleration/deceleration reference speed is set in parameter No. 7066
(AICC or AI nanoCC) or No.19520 (AI–HPCC or AI–nanoHPCC).
Because these parameters must be set in input unit, when the input unit
is changed, these parameters must be changed.
This method is used if the G05.1Q1 block or G05 P10000 block does not
have an F command.
