I'm making these small parts. This is my fixture I bolt to my rotary table.
So some of these parts have thicker tabs then others. The issue is the radius on the outter edge has to be the same as the 10mm id.
So what I am doing is dialing my fixture in zero to my mills spindle.
Then I move my X axis until the edge of my endmill is inline with the edge of my 10mm ID.
That way I can move my part the distance I need on my rotary table to get my thickness and maintain that radius.
However, this fixture sucks, it can rotate slightly. So what I am wondering is how I can improve this set up.
I was thinking milling a keyway inbetween the upper and lower half of my fixture so it cant rotate. Any other thoughts?
Then something I might be on my own with is, I need to rotate my part 180 degrees so I can mill the other side. Since I have my part offset on the rotary table, I can't just rotate the table. I'm kind of forced to rotate the part.
Any ideas on how I could accurately rotate the part besides scribing lines and eyeballing it?
Thanks for any ideas guys!
