Tool function T code
T code has two functions:
①→change automatically
②→execute tool offset
Code form T ΔΔ OO
ΔΔ:
Enter target tool number
OO:
Input tool offset number
G98:Spindle in mm/min
G99:Spindle in mm/r
G80:Cancel fixed cycle
Pausing function G04
G04 X5.0→dwell 5 s
G04 P5→dwell 5 ms
M3 S2000; spindle rotation
G98 F500 G01 X100; feedrate is 500
mm/min
G92 X50 W-20 F2 ;F is the thread
lead
G04 X2.0 ;delay 2 s
G99 G01 U10 F0.01 ;feedrate is 0.01
mm/r
G00 G80 Z50 M30 ;cancel this cycle
M5 ; spindle rotation stop

When specifying circle radii
with parameter R
Circles less than 180° are
assigned positive values
G02 X6.0 Y2.0 R50.0
Circles greater than 180° are
assigned negative values
G02 X6.0 Y2.0 R-50.0
Code G02 and G03
G02 circular interpolation CW
Motion path: Start point→end
point
CW (rear tool coordinate sys-
tem) / CCW (front tool coordinate
system)
G03 circular interpolation CCW
Motion path: Start point→end
point
CCW (rear tool coordinate sys-
tem) / CW (front tool coordinate
system)
You can specify the circle end
point in the following X/Z address
for both. You can also describe
circle radii with I, K incremental or
use parameter R to specify radii
directly.
Note:When using G291 to
activate ISO mode, you
must set machine data
MD10890=0,or the tool path
can not be implemented.
