Dimmensional Precision tests

Post by erapip »

I try to make the first test for the calib.scale 120mm (David original). You can see by yourself the differences.
Caliper approx 40.02mm
What about yours?

Hi,
how did you measure width in software?

Just in case you measure only a distance between two points:
Metrology tools such as GOM inspect offers you the possibility to simulate a caliper measurement:

You decide the regions you want to evaluate, and also some criteria about the caliper shape.

I think it's more accurate than checking a single distance beteween two points. (and it's free)

(I'm not a GOM representative, I just found it incredibly better than other tools for this kind of operations)

In the first pocture it measure dhe differences of 2 plains created in both sides. The third measure the distance in a cutting section. Thats why the valies are different.
Thanks ;)
