LMH,
Thanks for contacting us on the forum. I have taken a look at your image posted, downloaded the referenced file and played with the operation and tool settings until my results resembled yours in the image.

I got the following results:
First, for future reference, if at all possible, please attach a copy of the exact FreeCAD model file to which you are referring in the post. Having the exact file in the state in which the condition occurs provides the developers with a lot more information. Also, please include the tool information if possible - type, diameter, etc..
Otherwise, I can say that the paths are correct on the left side of the model (using my attached image for reference). Based upon what I see in your image and mine, you have a ball nose (rounded end mill) tool selected for the operation - about a 6.35mm diameter cutter. You can see in the attached picture on the left, the cutter drops in Z height to accommodate the ball nose curvature of the cutter - to fit the corner of the model.
I do however see we need to adjust the path calculations on the right side(terminal side) of the model. If the tool were a standard end mill (as in the last picture), the current path would be correct. However, it needs to be adjusted for the ball nose cutter. Other cutter types would more than likely need the same adjustment on that right side when finishing the model. The paths on the right should mirror those on the left in this situation.
Again, thanks for the feedback, Sir. I will work on the solution as time permits. I am limited on time for the next few days, but will have more time in the next few weeks.
I'll have to attach the model file I used for the screen shots later. Network restrictions on this machine hinder uploading the file to third-party site and giving you a link. I'll do that when I have access to my normal work station, and update this post accordingly.
