6. Interpolation Functions
6.6 Helical Interpolation
54
The plane for an additional axis can be selected as with circular interpolation.
UY plane circular, Z axis linear
Command the U, Y and Z axis addresses in the G02 (G03) and G19 (plane selection
G code) mode.
In addition to the basic command methods above, the command methods following the
program example can be used. Refer to the section "6.3 plane selection" for the arc planes
selected with these command methods.
