Taking previous stock into consideration

[amazecpk]

I have a two setup operation I want to run

The first setup gets rid of the bulk of the material with a standard 1/4in end mill. I have this set to have stock to leave at 0.25in

The second setup swaps out the tool for a bowl bit to give me rounded edges for the remaining material.

The final operation should be run with multiple steps set to 0.125in

The issue is the second setup isn't taking into consideration the previous stock that was removed. It is trying to mill out the same bulk of material the previous operation did

Second setup does have mode set to From Preceding Setup, and Continue Rest Machining selected

Also enabling Rest Machining in the geometry tab of the second setup does not generate any toolpaths. I assume this is intended for using different sized end mills rather than completing operations on the Z a xis

First setup:

Second setup:

I can get away with this if i setup offsets for the second setup, but I'm looking for a less clunky solution if possible.

That's because the 2D toolpaths are not aware of what stock is or isn't left on the part. However, the 3D toolpaths ARE aware of this extra material and should do a better job of it.

Thank you. a 3D pocket operation worked out well. Good to know about the differences between 2D operations, and 3D. Is there a resource that goes over the other differences between the two? Thanks
