[X9] Undercut with Slot Cutter using Surface Flowline Cutting Wrong Side

[MaximumOpticalClarity]

Hey yall, X9 user here.

I'm trying to use a slot cutter to surface the drafted conical surface on this part.

I've got it generating toolpaths as you can see from the screenshots but I am struggling to get it to use the upper part of the tool instead of the lower one. Check out the screen shot.

The toolpaths are in the right shape but wrong size and location. It seems to be using the bottom of the slot cutter instead of the top. Any ideas? Any hints on undercutting in X9 in general?

I no longer have X9 installed so can't be much help in a file way....

How is the tool defined? As a standard tool or as a custom tool?

i would also create that as a single surface as well....

Watch your flowline lines and make sure they are on the outside and not the inside

I still have X9 installed.  Can you share the file?  I just did this last week on several part types.  I'll throw a few paths on there.

I think you need to check the box for allow undercuts

Try defining the tool as a full radius tool. That is about the only way to get the path to not use the tool bottom as the contact point. To machine the full surface with the tool you defined, you would have to extend the surface by the width of your tool.

i've also in situations like this, transformed / created wireframe geometry on tool center and use for example a 2d swept with a zero or .0001 dia tool.

Threw a test file together....a file would be helpful it's something in the settings

I've offset surfaces, created a path on bottom plane, then used the backplot geo to drive from the center of the tool.

Guest,

I did this very same thing with the below settings. Someone told me this can be done with contour but I cannot figure it out.
