5.5.6 Scaling

Scaling applies only to the current program.

Besides, you can select between a new and an additive scaling.

With a new scaling, all scalings defined so far are deselected.

An additive scaling works incremental to the current selected scaling.

You can specify a scale factor for the active machining plane as well as for

the tool axis. The programme coordinates are then multiplied by this factor.

Note that the scaling always refer to the zero point of the workpiece.

For example, if you increase the size of a pocket whose center point does

not coincide with the zero point, scaling will shift the center of the pocket.
