Looking For Some Help :-)
Looking For Some Help :-)
(OP)
Hi,
I'm hoping someone can help? I'm studying ASME and geometric tolerancing and the book I have mentions a study done by a ELECTRONICS MEASURING DEVICES INC, done in 1989 to verify surface forms.
The paragraph reads;
According to a study done by Electronic Measuring Devices Inc, in 1988, it requires an average of 191 points per square inch to achieve a 90% certainty in the collected data reaults when inspecting a simple flatness control. An average of 102 points per square inch were needed to achieve a 85% certainty of the actual value of flatness.
I'm trying to find said study!! Googling has brought up very little information, any help would be great!
Cheers
