We are doing a short run project for a company. We are a stamping factory. They want to stamp out a flat "V" shaped retention spring out of 0.018" thick steel and measure 0.010" flatness,
unrestrained. I usually deal with material that is thicker than this. Anyone have any ideas?
BIGWIG7 Based on my assumption on the size (OP & sketch shows .018" thick so it can't be much larger that 1/2" squared) you would simply zero on the highest point on the top side of the part and look for the lowest point on the top side of the part. One could assume that could be done by simply changing the focus (our Starrett comparators will move almost 3" for adjusting the focus) to see the whole part
dwade How do take into account if the part is potato chip and you are only looking at it in one viewplane? You won't be able to see the "bow". I'm not trying to be difficult here I'm just trying to work out the best way to check this thing if I were in OP's shoes. *smooches*
