Waterfall effect on parallel tool path

[tgford58]

I have a deep pocket and angled wall that needs to be completed.  I employed the Parallel tool path which will track up and down the wall as I'd like but if I mark Contact point boundary I get the waterfall effect to the inside of the part.  Using Contact Only does not allow the cutter to machine to the extents of the feature.

To be frank, I've changed enough parameters that I probably have the tool path jacked up but I can't see how to correct this issue?

Can someone help me please?

Couple options:

1) Turn on "Touch/Avoid Faces" and select the vertical walls to Avoid. Result:

Option #2: Use a Patch Surface that is larger than the surface to machine, but this time using "Touch" and selecting that face:

I attached with a couple paths added. The second one I would add a little to boundary offset to make sure it cuts all the way to bottom of surface.

For some reason I can't get this file to import to my Fusion??

And the second file you sent is now gone?

I used the Avoid/Touch.  I've hit this before and simply forgot that facility.

I am just starting to work with Patch surfaces.  How do I generate the larger feature?  I looked at using offsets in Design mode, constrain ends then patch inside.  Just not sure I'm starting right.

Give this a watch. I figured it was easier to demonstrate than to type it out 😉

I don't know why your file is exporting that way. Others don't🤔
