G19 (J-K Plane Selection)
Table 3-7
Command Horizontal Axis Vertical Axis
G19 Y0 X0 Y X
G19 Y0 A0 Y A
G19 Y0 B0 Y B
G19 Y0 C0 Y C
G19 X0 Z0 X Z
G19 A0 Z0 A Z
G19 B0 Z0 B Z
G19 C0 Z0 C Z
G19 Y0 Z0 (or G19) Y Z
Note:
1. In a plane layout command, there is no fixed sequence for the horizontal and
vertical axes. EX.: G17 X0 Z0 = G17 Z0 X0
2. In G17, always use the IJ value to indicate the radial increment from the start point
of an arc.
In G18, always use the KI value to indicate the radial increment from the start
point of an arc.
In G19, always use the JK value to indicate the radial increment from the start
point of an arc.
EX.:
G17 X0 Z0 (Select X/Z plane)
G02 X10. Z10. J10. (J stands for the radial increment of the arc from the
starting point of the vertical axis (Z-axis) (to the
center of the arc).
