Have some more interesting little pieces we made a few days ago in our Haas VF0.
These again are some prototype parts.....no clue as to their use....was WAY too busy at the time to chat with the engineer, just got'em done!
Pictures can always be deceiving with regard to size thus the Sharpie in the back ground for reference.
These parts are a one piece construction, made from 303 Stainless Steel.
The small post diameter you see is a .249"/.2495" dia. with a #10-32 tapped hole in it. We interpolated the .249" dia. and you may not even notice it, but at the shoulder there is a .032" wide x .010" deep relief groove as well that was interpolated using a .032" wide keyseat cutter.
The other hole thru you see is a .187"/.1875" dia. which we simply reamed. The rest of the part geometry was nothing critical, but the large radius (size being a relative thing) was a .270" radius MINIMUM, so we had to mill that to size rather than simply use a corner rounding end mill.
Workholding can always be a thoughtful and interesting challenge when working with small parts, especially when configured in an odd shape, such as these pieces.
Overall it was a fun job, and really only took a few minutes a piece to make once programmed and all set-up.
