Re: [CAD_CAM_EDM_DRO] I'm impressed. Anyone want to write the G-Code for this?

Actually, I'm not sure you need CNC to do this. If it was all done on a
milling machine, then, yes. I think it could all be done on a lathe,
with a lot of repositioning. A fixture to hold it might be helpful there,
as
you have to turn it a bunch of times. The ID of the bores looks cylindrical

to me, but I can't be sure. I think you'd do the bores starting from the
smallest diameter and deepest, and then work outward, sort of burning
your bridges as you go, as the last of 6 bores is done, the inner part
is left weakly supported. But, then you won't be stressing it any more, as
you will be working on the next cube outward.

On a CNC mill, you could probably do all the bores on one face at a time,
only having to position the part 6 times. The last face might be tricky,
requiring slower feed to avoid bending the outer cube, although it looks
like it has enough material to be fairly rigid.

I might have to try one of these, sometime!
