You can't get rotary motion within a canned cycle. The documentation alludes to this: Rotational axis words are allowed in canned cycles, but it is better to omit them. If rotational axis words are used, the numbers must be the same as the current position numbers so that the

Gentlemen, I can see many cases of ABC motion in a canned cycle being very useful ie. a cylindrical part in a rotary table. A canned cycle could easily drill multiple holes in a cylindrical part with multiple holes in the periphery of the part. I can only imagine a few ABC configurations where
