3D Adaptive Cleaning Questions/Help

[neinspam2XVWZ]

I have a relatively simple body to machine, should be easy right.  Some things about 3D adaptive I find puzzling.

1) The two small raised circles in the attached are stock top.  So why does the 1/4" mill roughing operation mill the tops?

2) The upper left circle is milled with the 1/4" bit then again with the 1/16th bit even though stock to leave is set to zero for the first operation.

3) with stock to leave set to zero or off the circle perimeters are still being cleaned up with the second operation 1/16 bit.  should the 1/4 " bit get everything on a simple circle?

4) the 1/16 bit cleans up some of the raised lettering, jumps to the upper left raised area resurfaces the face then returns to finish the raised letters.  isn't it more efficient to finish the letters in one shot in stead of jumping around?

Any clarity or pointers is appreciated.

Could you export and share your file?

It's milling the tops likely because you have your Top Height set to Stock Top. Changing it to "Model Top" should clear that out. The 1/16 tool is cutting everything, possibly because you don't have "Rest Machining" turned on. Seeing the file will be a great help in getting you sorted

Changing Stock Top to Model Top worked.  I'm a little confused because stock and model top should be equal. 

I'm still getting the 1/16 bit running a finishing pass on the upper left raised section.  I would have though the 1/4" would have taken care of it. 

Attached is the file.

Regarding the Stock vs Model Top:

 

For the 3D Adaptive: When you have both toolpaths going to the same level and neither one of them have Stock to Leave turned on, AND your tolerance is set to a generous .1mm, it's going to "see" material everywhere. Tighten up your tolerances and consider a touch of Stock to Leave on your rest tool. 
Or, change your boundaries, because there's nothing for you to machine on that island anyways 😉
