I am having some trouble with measuring accurate Diameter size, I have read some threads on this type of thing but the solutions provided pertain to mostly Bridge Type CMMs and I am using a Romer Arm. So I'm interested in any tips you guys may know of to get more accurate results. ... oh and it seems I have more trouble when working on sheet metal parts and I can imagine its due to the thickness of the material. Thanks in Advance
ok and all this stems from an Engineer asking me why the romer can not measure diameters properly, kinda hinting that I may be doing something incorrect etc. My argument was that it is very difficult to measure diameters on sheet metal parts, and the other was that when I measure the diameter of a hole with the biggest allowed pin gauge, it will drop 70 to 80% down into the hole and then get caught up, I think its due to the holes being tapered and not the machine accuracy
