Perpendicularity Length measurement
Perpendicularity Length measurement
(OP)
Hi guys, I am using a Mitutoyo QM-Data200 2D data processing unit on a horizontal projector to measure parts. When I go to measure perpendicularity between two features, the machine requires me to input a length value. I assume this length is the length of the feature I am checking the perpendicularity of, but it seems odd to me that they would ask something that the machine should be able to easily calculate. I have gone through the user manual, and it does not address perpendicularity measurement. From what I can find in the ASME Y14.5-1994 spec, no length is required when measuring perpendicularity, so why does the machine want a length value here?

So that's probably why it needs to know the length. I don't know enough about the inspection machine to say why it can't figure it out for itself if that feature has already been measured for length.

However I'd have thought even if that's the reason, it's default should be the feature length.
