Hi,
Need some advice on some good source for evaluating Flatness of for example a surface plate by some numerical method, by hand or excel.
Straightness seem straight forward but its the connecting of data sets och evaluating the resulting minimum flatness the gives me some headache.
As this been done for decades there should be some good book / reference / instruction on it somewhere to be found? I´ve googled a fair bit but my thinking is that electronic A-C´s were common already prior to internet, as not much shows up beyond basic straightness and various possible set-ups, but little on actual hands-on evaluation. Plenty of expensive programs though...
At my hand:
A one axis 0,5" analog auto collimator with two mirrors, one perpendicular on stand and a front end mounted 90degree deflector.
It appears o be in good working order, lights, adjustments etc. I assume it would benefit from a calibration before doing any real work but first I´d like to see I can master the the actal data evaluation.
Thanks for any input!
