Scaling factor (G72)
7.6.2 Scaling factor applied to one or more axes.
The programming format is:
G72 X...C 5.5
After G72 the axis or axes and the required scaling factor are programmed.
All blocks programmed after G72 are treated by the CNC as follows :
1. The CNC calculates the movement of all the axes in relation to the programmed path and
compensation.
2. It then applies the scaling factor indicated to the calculated movement of the corresponding axis
or axes.
If the scaling factor is applied on one or more axes, the CNC will apply the scaling factor indicated
both to the movement of the corresponding axis or axes and to their feedrate.
If, within the same program, both scaling factor types are applied, the one applied to all the axes
and the one for one or several axes, the CNC applies a scaling factor equal to the product of the
two scaling factors programmed for this axis to the axis or axes affected by both types.
Function G72 is modal and will be cancelled when the CNC is turned on, after executing M02, M30
or after an EMERGENCY or RESET.
This type of scaling factor is ignored when simulating without moving the axes.
As it can be observed, the tool path does not coincide with the required path, as the scaling
factor is applied to the calculated movement.
Application of the scaling factor to a plane axis, working with tool radius compensation.
