11.8 AXIS-SPECIFIC SCALING
(Cycle 26)
Effect
With Cycle 26 you can account for shrinkage and oversize factors for
each axis.
The SCALING FACTOR becomes effective as soon as it is defined in
the program. It is also effective in the Positioning with MDI mode of
operation. The active scaling factor is shown in the additional status
display.
Reset
Program the SCALING FACTOR cycle once again with a scaling factor
of 1 for the same axis.
Please note while programming:
X
Y
CC
Coordinate axes sharing coordinates for arcs must be
enlarged or reduced by the same factor.
You can program each coordinate axis with its own axis-
specific scaling factor.
In addition, you can enter the coordinates of a center for all
scaling factors.
The size of the contour is enlarged or reduced with
reference to the center, and not necessarily (as in Cycle 11
SCALING) with reference to the active datum.
