Fusion

I recently finished a project where I had a bunch of pieces nested that needed to have 2D Adaptive Pockets ( and contours ) milled out - In 3D the picture below it would be the pieces making up the horizontal ring structure.
The pockets in question are what allows the 6 pieces per ring to be joined flush so there's nothing around them except for one wall.
As can be seen with the picture above at some point the bit went through the stock material at full pocket depth which if it weren't for MDF being such a forgiving material would certainly have wrecked my Endmill :°
The thing that bothers me the most is that like 95% of the time the operation would raise the bit before continuing to another section but every once in a while ( while nearby? ) it would go straight through the material to reach the next pocket or contour without lifting the Z-Axis.
How can this be prevented?
Other than that the project came out fine...

Going to be hard to help without the model, can you share the f3d file? Did the problem show in the simulation in Fusion? Safest bet is use 3d adaptive it's just as quick to set up and is stock aware. 2d ops don't care about stock so if you don't set it all up correctly it'll go through the stock. Could go on with more guesses but I rather see the design and not need to guess.

Completely (OK, mostly) unrelated to your question.... not a criticism at all just food for thought:
When designing process vessels (large reactors, etc) for vacuum, stiffening rings are almost always installed on the outside. It doesn't take much to keep the cylindrical shape of a thin-wall vessel intact. This is the dust bin below our smaller dust collection - (3) 1/8" rings made out of scrap material (Dibond). They're just a friction fit and have been there for maybe 7 years. Every once in a while one gets knocked off when emptying the bin, but it's easy enough to pop back on. Hot melt glue would also help. This way the bin becomes super easy to empty, because it's smooth on the inside. FWIW... it's a 5HP cyclone unit hung from the ceiling above.

I have seen a similar problem with 2d contour and the stay down distance letting the toolpath go straight between profiles. Might want to set your default to zero.
