Finished this drawing for my current project. The Machining is still under way, but this is a little teaser for everyone to look at. More in a week or so.
These two are the second and third
installments before I move on to a bigger project. This first one is more a
technical achievement than anything.
The machining of the center piece on this one involved writing a program
that wrapped a helix around the sphere. rather than run the cut straight
through It took quite a while to figure out the tool path geometry because
it involved changing the helix as the cutter progressed deeper into the work
piece. Not an easy thing for me to solve. Also making the actual cuts in
Stainless steel called for some extra care as well.
