Currently we have this fixture on posts which hold it suspended above
a surface plate.... (the posts are very accurately ground etc.)
then we use a 0.0001" dial indicator on a stand... not sure the name of it,
but its an indicator holder that slides around on the top of a surface plate.
we can run that indicator back and forth under the fixture that holds the detail, and tell how flat the detail is sitting in the fixture. This allows us to then make adustments to the block until it is flat.
I am trying to figure out how to measure this automatically..... |
