- Scaling along each axis at a different rate of magnification
For a command in scaling mode, the following command specifies
scaling with the center at a point specified by X_Y_Z_ at the scaling
magnification rates specified in I_J_K. If scaling magnification rates I,
J, and K are not specified, the magnification set in parameter No. 6421
is used.

axis Y axis and Z axis
respectively
C

- Least input increment for specifying rates of magnification
The least input increment for specifying rates of magnification is 0.001
or 0.00001. When bit 1 (SCR) of parameter No. 6400 is set to 0, 0.0001
is used; when the bit is set to 1, 0.001 is used.
- Tool offset
This scaling is not applicable to cutter compensation values, tool length
offset values, and tool offset values.
