The machine does it easily!
What's the difference?

Hi Amir,
Just to clarify, the drawing you attached looks like it is showing a part of a helical slot. The circular component is true to the xy plane. The z motion is a separate linear motion.
So in the three standard working planes, an arc, even as part of a helix, is only handled by two axes. Arcing in a non-standard working plane is a feature more commonly used on 5-axis machines I suppose. It could be an optional extra on your control but probably not worth paying for.
So how are you going to program it?

Thank you for the information, actually I kinda gave up, it really annoyed me! I was working on it for a whole week standing up to machine and change every line more than 10 times.
And I'm not convinced yet.. how can our controls be that weak..??
Anyway there is a way to get it to work and it is dividing arcs to polylines, a little macro could do that easily, maybe someday I wrote it. not on the mood and so busy at the moment :/

It looks like a simple helical interpolation. Option on some machines.

I've tried your sample with my CNC and I've got this result:

something wrong in program ?
