11.10 General scaling factor
It may be used to enlarge or reduce the scale of the programmed paths and contours. This
permits using a single program to make sets of similar profiles of different dimensions.
The general scaling factor is applied to all the axes of the channel. After activating the scaling
factor, all the programmed coordinates will be multiplied by the defined scaling factor until
it is canceled or a new scaling factor is programmed.
Activate the scaling factor
The general scaling factor may be activated using the commands G72 or #SCALE. Either
command may be used.
Although there are two different commands, the scaling factor is the same; i.e. the scaling
factor programmed with G72modifies the one programmed with #SCALEand vice versa.
Programming with G72.
Program function G72 and then the scaling factor set by parameter Sas follows.
G72 S<scale>
Programming function G72 alone or a scaling factor of ·0· or ·1· cancels the active scaling
factor.
Parameter "S" that sets the scaling factor must be programmed after function G72. If
programmed before, it will be interpreted as spindle speed.
Programming with #SCALE.
Program the instruction #SCALEand then the scaling factor as follows. The brackets must
be programmed.
#SCALE [<scale>]
Programming a scaling factor of ·0· or ·1· cancels the active scaling factor.
Cancel the scaling factor
The general scaling factor is canceled using the same commands G72 or #SCALE, setting
a scaling factor of ·0· or ·1·. When using function G72, the scaling factor is also canceled
by programming it alone in the block.
Considerations
Activating the machine coordinate system (#MCS ON) cancels the scaling factor temporarily
until the machine coordinate system is canceled (#MCS OFF).
While the machine coordinate system is active, the scaling factor can neither be activated
nor modified.
Properties
The scaling factor stays active until canceled with another scaling factor.
On power-up, after executing an M02 or M30, and after an EMERGENCY or RESET, the
CNC cancels the active scaling factor.
