Flatness: How To?

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?

  • I would try to measure it directly on the granite, but with a probe angle important (like A80, for example, to limit the force.
    You could also decrease the trigger force and the upper force.
    About 0.5 mm f steel shouldn't be too soft (IMO).

    If you can find an "APOLLO" probe, it will be ok, the probing force is close to zero !!!!!
