G50, G51 - Scale mode

The G51 command allows you to use the scale mode in numerical control systems. For each axis, it is possible to specify a scaling factor.
Command format: G51 X Y Z I J K
I - scale for X
J - scale for Y
K - scale for Z
X Y Z - coordinates of the center of scaling

Command format: G51 X Y Z A B C P
P - scale for axes X Y Z A B C
X Y Z A B C - coordinates of the center of scaling

The G50 command allows you to cancel the scaling mode with numerical control systems (CNC) of machines.
Consider an example of using the G50 and G51 commands below: First, create a simple square program.
