Changed behavior in 3D adaptive

[jagSJMV8]

We are milling a part where the 3D adaptive behaves real odd. The protrusions on top are 5mm but 3D adaptive only does side milling, and in the mills 13 down from the facing rather than the 5mm

What are we doing wrong when the machining ignores part of the area. We lost CAM libraries and have strange behavior since the last update.

I have made a mockup of the part

It'll be a combination of having Flat Area Detection on and minimum/fine stepdown value.

Removing Flat Area detection does not change things.

We always run flat area detection to make sure we don't break tools in subsequent processes.

set Minimum Axial Engagement to 0

and Top Height to Stock top

I very rarely use flat area detection, because it often results in wasted time cutting a level that does not need to be cut for the whole part (say there is a small island in 1 area of the part, it will cut at that Z level the entire part).  I prefer to create more operation, for each Z level, that way it does not cut something 0.1" deep on the whole part.  Depending on the part, this can save a lot of time.  But, that does not solve your issue... sorry... just thought I've give my 2 cents, for me, flat area detection  is in general pretty bad for efficiency.

Thanks!

We use the machine for 1-2 parts per week so for us it is more about
flexibility and not braking stuff than efficiency.

Great Thanks!

Anywhere that I can read about the logic, because I get choked time after time thinking I understand what Fusion is supposed to do and how to machine the areas we want to machine?
