A finishing issue

[adam.j.mclachlan]

Hi there, i am fairly new to fusion 360 and i was wondering if anyone would have any suggestions on how to finish this area shown below:

i have tried a few different toolpaths such as parallel, scallop and contour but it always contacts the back wall.

If anyone has any suggestions i would really appreciated them, thank you.

Ball end mill depth is from tip of the tool but cut at the selected contour is 3 mm  above tip (6 mm end mill diameter).

By offsetting tip down less then 3 mm, I am leaving stock on other surface undisturbed while machining the vertical wall to near finish radial dimension.

This provides relief for when tool is finishing both surfaces, otherwise, when tool is at the edge of fillet, it is also in contact with vertical wall and I don't want it to negotiate all that stock on vertical wall in one pass.

Now, cutting aluminum makes it so much less critical but still, without Trace tool path, you would likely see more chatter on part then this way.
