FANUC Series 16i/18i/21i –TB,
Cylindrical interpolation by the developed
cylindrical surface command
Command of rotary axis is distance on the developed cylindrical surface (parameter No.3454#2 DTO=1)
Command of rotary axis is distance on the developed cylindrical surface in cylindrical
interpolation mode. It is change command unit by inch (inch input) or by metric (metric input).
Plane selection (G17,G18,G19)
Use parameter No. 1002 to specify whether the rotation axis is the X–, Y–, or Z–axis, or an
axis parallel to one of these axes. Specify the G code to select a plane for which the rotation axis
is the specified linear axis.
For example, when the rotation axis is an axis parallel to the X–axis, G17 must specify an Xp–
Yp plane, which is a plane defined by the rotation axis and the Y–axis or an axis parallel to the
Only one rotation axis can be set for cylindrical interpolation.
A feedrate specified in the cylindrical interpolation mode is a speed on the
developed cylindrical surface.
Circular interpolation (G02, G03)
In the cylindrical interpolation mode, circular interpolation is possible with the rotation axis
Command of rotary axis is distance
on the developed cylindrical surface
The U–, V–, and W–axes (parallel with the basic axis) can
with G–codes B and C.。
