Seems that a few of us have questions about the 4th axis.

I don't know which toolpath to use.

The picture cnczone1 shows the raw material and the final part

The file CNCzone2 shows what I can do with simple contour toolpaths, but I can't take off the material between the two flats. I pre-machined my raw material.

The 4th axis is parallel to the cylindrical axis of the part.

I guess I'd want to do is either :
1- do a cut as the 4th axis rotates, move down the part and do another cut
or
2- Do cuts along the axis and the rotate the 4th axis between each cut.

but I don't know which toolpath to choose( I've tried all of them and looked in the help, which was no help)

Any ideas?
