I'm trying to check the large radius (25mm +/-3mm) with a small arc (15 degrees). So far I've used auto circle and auto edge points.
The auto circle keeps reporting R5-R6mm. I attempted to change a few things:
- lighting for better contrast. No luck, working with a plastic part, the color is very uniform.
- increase the number of coverage active hits from 4 to 15. Still getting a very small radius.
I wasn't sure what else to change, so I switched to using auto edge points. I'm still getting a small radius: R5-R5.204.
- despite having the same lighting settings for each auto edge point, I get an error message for some of them saying that an edge can't be found. I then attempted to customize the lighting settings for each point so that I'd get no error messages when checking the radius. Now I'm getting edge error messages for a point that was reporting fine just a moment ago. There's no consistency here; I'm puzzled.
So I suppose after all of that rambling, my question is: what are some strategies you guys use to find radii assuming you cannot use the radius gage in Live View because a radius is too big?
Set your origin to the locii of the design radius, check 2 or 3 points for proper radius (distance from origin to points). Don't try forming a circle with 15 degrees
Offsetting the alignment to the theoretical locii of the radius worked and then finding the distance from that to the measured points worked like a charm. Thanks a ton
tking!
