3.21 Scaling (G36/G37)
A programmed figure can be magnified or reduced.(scaling)
The dimensions specified with X_, Y_, and Z_ can each be scaled up or down with the same or
different rates of magnification. The magnification rate can be specified in the program.
Unless specified in the program, the magnification rate specified in the parameter is applied.

R_: scaling magnification.
P1` P2` P3` P4` magnify to P1 P2 P3 P4,R=P0P4`/P0P4. When P1 P2 P3 P4 reduce to P1` P2`
P3` P4`, R=P0P4/P0P4`. So: R<1 when magnifying, R>1 when reducing,R=1 can be default.
Note: 1.Specify G36 in a separate block. After the figure is enlarged or reduced, specify G37 to cancel
the scaling mode.
2.If someone axis didn’t specify, this axis won’t scaling.
3.the scaling is invalid for value of tool compensation & tool offset.
4.In scaling mode, G27, G28, G61& G30, or commands related to the Coordinate system(G52-G59)
must not be specified. When any of these G codes is necessary, specify it after canceling scaling mode.
