Adding a spring pass to a helix bore

[RDEMIDON]

Is there a way to add a spring pass to a helix bore? I am trying to add an extra pass or 2 at final depth to help hold a tight tolerance. If I use the rough and finish option, it wants to retract after the rough pass and then run the finish pass. I would like it to run the rough pass and then stay down and just run a spring pass. Is this possible?

Try setting the overlap to the circumference of the centerline of the tool path

Or maybe the circle mill tpath,...

Set your roughing step over to the radius of the arc, activate helical entry, set the max radius of the of the helix to radius of the arc,..

In the finishing settings you can setup the semi finish passes and also activate finish, for spring passes set the spacing to zero,..

If you don't want retracts set the check box for keep the tool down,..

If you want the tool to return to center before each pass, activate transitions, turn on lead in/out and select start at center,..

Thanks for your help guys. Works just like I wanted it to.

I just do a contour ramp with a stepover of zero, lead-in/out on first/last only, finish passes at final depth.
