Hello everyone. I having a hard time in deciding measurements for parallelism of the flat glass. I have a glass of diameter 20mm, thickness 2mm. While the parallelism is 1′. Is quite tight for production. Previously for parallelism, we are using the dial gauge to measure it, where we calculate the angle to height difference with the use of Trigonometry Concept. So, any suggestion from everyone for the measurement of this? Where it is quite fast for mass production? Instead of using CMM for it.
