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?

  • Do you need to measure a lot of these? If not id suggest just leveling it out with some adjustable legs and run an indicator over it.


    No. Most likely 30 pieces for a capability study on flatness.

    Honestly, that was my thought as well with stands and an indicator rather than a CMM. I just wanted to know if anyone has done anything like this on an automated piece of equipment.
