Well ya, it would.

You have .005" stock to leave, so the contours overlap. At which point, the offending moves are discarded. I actually would expect to see all internal moves removed (and they do if I set Stock to Leave to .0051")

Oh that's unfortunate. Figured if the tool isn't going to hit anything and has .005" of clearance it would just mill what I told it to.

 

Perhaps some investigation on why they didn't all get trimmed?

Floating point and rounding will be the answer, would stake a fair bit of $ on it

I encountered this on a old program. a program that I have successfylly posted (and producing parts with)
Now I opended it up again and noticed that 2 operations in 2 different setups (multiple different parts that look almost the same) had an error.

Both of them where a 0,8mm endmill in a 0,9mm slot. Similar (as in exact the same) operations with a 0,5mm endmill in a 0,6mm slot still works
with some fiddeling i managed to get 1/3 of the slots to produce a toolpath. (of 66)

its a bit frustrating that operation  that you manage to get working all of a sudden decides to not work and you have no clue why

@rhdfmail could you share your Fusion file here?

cant share the original but I made a new project with just the problematic features and corresponding operations.

This is how I ran them last time, and no errors

I've opened up CAM-44709 to investigate this issue.

 

As a workaround, you could program the one contour that is working and then put it into a Pattern > Rotation

Good tip with the "workaround"
