How about that:

... and here's a more parametric way to do it (just set the angle in the spreadsheet and everything auto-updates) - went for the simplest corner relief (equivalent to what dogbone calls "tbone short edge", I think)

Hi Guido,

if you make "dogbones" this way, you have to make the entry to the pocket bigger as the tooldiameter to. :)

Niceeeee!

Yeah, you're right. I realized that after posting the drawing... :oops:

If you want to do it in a certain angle, you can do it like this. You simply have to change the angle constraint.
The construction diameter assures that the opening is exactly the half circle, so that nothing is lost: making it the opening wider wouldn't remove enough material, making it narrower would require a hole more off than necessary which would take away too much material.

Thanks! ;)

With this method there is a little bit less material to be removed, if compared to your previous proposal.

It can be an advantage when one has to produce hundred of pieces. In my case I only have to mill few exemplars, so the two approaches are more or less equivalent.

That's what I would have guessed, I did it rather to fully understand the problem dogbone myself. The last solution has the advantage that your are free to decide where to leave more material, at the end or at the sides; perhaps influenced by other mechanical conditions.

I haven't tried this myself but could you just extend the arc on both ends by a tiny straight segment. Just enough so the dogbone dressup has G1 moves to work with?
