Yes, I have done this. I received a board where the cutting operation
was missed. They want the board layout separated by 10mils for cutting.
I used a centre drill to V score the boards, as that's what I had on
hand. I scored the board on both sides, and it snapped apart very easily.
The most difficult part was setting it all up on the mill.
Cheers,
Peter.
