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.
Resetting
Program the SCALING cycle once again with a scaling factor of 1
for the same axis.
Please note while programming:
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.
