Scaling with TRANS SCALE

Application
With the TRANS SCALE function, you can scale contours or positions
and thus enlarge or reduce these uniformly. This enables you to
program shrinkage and oversize allowances, for example.
Use the TRANS SCALE RESET function to reset the scaling.

Description of function
Scaling is a modal function that is effective as soon as it has been
defined in the NC program.
Depending on the position of the workpiece datum, scaling is carried
out as follows:
Workpiece datum at the center of the contour:
The contour is scaled uniformly in all directions.
Workpiece datum at the bottom left of the contour:
The contour is scaled in the positive X and Y axis directions.
Workpiece datum at the top right of the contour:
The contour is scaled in the negative X and Y axis directions.
If you enter a scaling factor SCL less than 1, the contour will be
reduced in size. If you enter a scaling factor SCL greater than 1, the
contour will be enlarged.
When scaling, the control takes the coordinate input and dimensions
from all cycles into account.
If scaling is active, the control displays it on the TRANS tab of the
additional status display.
