Parameters
G50, G51 Scaling
These instructions magnifies or compresses a commanded shape.
The G50 and G51 scale the current coordinate system. G50 disables the scaling and G51 enables it. X,
Y, and Z parameters indicate the center point. If any of them is omitted, the omitted value is handled as
the current position. The values of X, Y, and Z parameters are handled as absolute position. The P
parameter indicates the magnification ratio of all of the X-, Y-, and Z-axis, whereas I, J, or K parameter
is the magnification ratio of each axis. The I, J, and K parameters are the magnification ratio of X-, Y-,
and Z-axis respectively. If any of I, J, and K parameters is omitted, the omitted value is handled as the
same size. P parameter is prioritized over I, J, and K parameters.
