CONVERSION B–63502EN/01
NC FUNCTION
156
X_Y_Z_ : Absolute command of
center coordinate value of
scaling
I_J_K_ : Magnification of scaling
of X axis, Y axis, and
Z axis
(Unit 0.001 or 0.00001 is
selected according to
the parameter.)
The magnification which can be
instructed is as follows.
±0.00001–±9.99999 or
±0.001–±999. 999
