13.20 Scaling; G50/G51
444
Precautions
(1) Scaling is not applied to the compensation amounts of tool radius compensation, tool position
compensation, tool length compensation and the like. (Compensation is calculated for the
shape after scaling.)
(2) Scaling is valid for only the movement command in automatic operation. It is invalid for manual
movement.
(3) For X, Y and Z, scaling is valid for only the specified axes and is not applied to the axes not
specified.
(4) When an arc is commanded and scaling is valid for one of the two axes configuring the arc
plane, a program error (P70) will occur.
(5) When M02 or M30 is commanded, or when NC reset is carried out during the scaling mode,
the mode switches to a cancel mode.
(6) When the coordinate system is shifted (G92, G52 command) during scaling, the scaling center
is also shifted by the difference amount.
(7) If manual interruption is made during scaling, manual ABS selection is ignored for the
movement followed by an incremental value command and operation performed is the same
as in manual ABS OFF.
