Chamfer with mill tool

Hello When I start making tool path for this type of object it's just make circles strait down, without compensation to object itself I unable use pocket or profile to get needed result

P.S. testpiece_goal.FCStd it's file that I try to cut
testpiece.FCStd it's what I made to achieve that, but I need create manually new path for each step down, that's why bunch raintagles of different size. For now I have only milling tool for CNC

UPDATE

Endmill tool tip 20mm Diameter

So here is new file Eye_hole_smoth_Inckscape.FCStd. I used 6 profile to make path for chamfer
Is there any other way make it automatically with pockets or etc? My attempt using pockets are failed, I wish I had tool for that but I must work with what I have for now.

If you post to the FreeCAD forum, please do everything that makes helping easier:

- attach your FreeCAD infos
- attach a file showing your issue
- show an image (done, at least partially)
- describe in detail what you have done / intend to do; here we don't even know which Path operation you tried.
- copy error messages into a code block in the post.

So I need make something like this with mill tool but not generate every new mm with new job or at least to know how automate

I took a look at your file.

The problem is that the basic model is a bunch of simple rectangles, not some sort of solid.

FreeCAD can deal with this, but I do not think it can handle a set of separate outline shapes as a single object.

If you create a solid with all the steps then a single Job can be used. It may require separate profile or pocket operations, but all in one Job.

Chamfering is a profile operation that requires a tool radius offset.
* The diameter to be taken into account is that of the end of the tool (D1)
* The TLO is measured from the face of D1,
* The amount of chamfer is determined by the tool plunge in Z.
* The edge to be chamfered must be prepared before (contouring, pocket, etc.)

I do not believe the OP is looking for something that would commonly be called a chamfer. It is more of a stairstep shape.

I use Chamfer as toolpath guide for path/job
