G51 is scaling on, while G50 is scaling off (Default: G50).
The range of scaling: 0.000001-99.999999
For example:
I0.666666 denotes that X is scaled down to 0.666666 times of the original dimension, while J3
denotes that Y is scaled up to 3 times of the original dimension.
When using the scaling command, pay attention to the followings:
 Don’t set the scale factor as 0, or else an alarm will appear.

Scaling function has no effect on compensation value.

When executing cutter radius compensation C, the scaling instruction (G51)
can’t be specified.

A canned cycle cannot be executed together with the scaling of Z-axis. If so, an alarm will appear.

These G codes cannot be used in the execution process of scaling function: G28, G29, G53, and
G92, or else the outcome may contain an error.

If there is G51 in the program without G50, the scaling function will be automatically closed at the
end of the program.
