Maybe this is related, but none of the Path Workbench operations seem to want to take away all of the cone. Adaptive was best, but it stop shorts of going all the way to the point. Did you try 3D Pocket or 3D Surface? They should get down as far as the tool diameter will allow. Gene Gene 3D Surface...

3D Surface with a ball-end mill should be able to deal with this shape. Gene Gene , thank you so much! For those that may have a similar issue, the path operation "3D Surface" is hidden by default. I had to follow the instructions here https://wiki.freecad.org/Path_Surfacehttps://wiki.fre...

Yes that's better. I should have asked this earlier: Why don't you do it all in PartDesign with a subtracvtive cone? I did switch to PartDesign, just to subtract the cone though. I'm still learning my way around Freecad, I started with a body and pad. Maybe this is related, but none of the Path Wor...

Are you talking about the conical pocket I have on the right? I mean this: Snip macro screenshot-12f1be.png Be thorough with your wording: It's not a pocket, it is a cut. chrisb Ah, my mistake. Is the attached what I should be seeing? That's my tree after adding a cone and applying a boolean differ...

Chris,

Are you talking about the conical pocket I have on the right?

Hello, What is the proper way to configure a path operation to remove the stock above this horizontal conical feature of my pinball playfield? I tried (physically cut) a face mill operation, and that did not go well. Essentially took off the entire rectangle that sizes the outside perimeter of the c...

Most likely a floating point rounding error. Try setting the 1/8 mill to a diameter of 0.1249999. If it appears that the cutter will not fit then no path will be created. FreeCAD does not employ the typical floating point precision of 15 or 16 digits for calculations. There are many places where th...
