7.10 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
G72
modifies the one
programmed with
#SCALE
and vice versa.
Programming with
G72
.
Program function
G72
and then the scaling factor set by parameter
S
as follows.
G72 S<scale>
Programming function G72 alone or a scaling factor of ·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
#SCALE
and then the scaling factor as follows.
The brackets must be programmed.
#SCALE [<scale>]
Programming a scaling factor of ·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 ·1·.
When using function
G72
, the scaling factor is also canceled by
programming it alone in the block.
