I just read through this post and it remindes me of a control for a machinemI built.
The customer wanted this thing to have 2 micron accuracy.For the process and machine
I knew that this was a joke but what the heck.I bought some linear guides and servo/controls
and put it all together (2 guides and servos 25k$ usd.).Now this thing had a dro that the operator could look at to monitor the operation.I had a call a few weeks after it was all up and running.Seems that every time some one walked by the indicated value on the dro would bounce around.All kinds of crap started to fly.My solution ;
I had some one put black tape over the last 2 digits on the dro.Now the error was gone and the machine worked great.The process in reality was only measured with a .001" micrometer .
2 microns is about .00008 in.
