Hi, I am dimensioning an o-ring grove and parkers catalog says the max eccentricity is .002 and states this is TIR between the groove and adjacent diameter. I think TIR is total indicator reading, but is this total runout (two arrows) or circular runout (one arrow)?

Thanks

Jim,

Irregular features of size? You mean those features that don't necessarily have opposed points, that we can't apply size tolerances to, that really aren't features of size? Don't get me started on those!

Have a good weekend as well. I'll be watching the Canucks and Black Hawks game tonight while the barbecue is going!

I believe the caliper rule is one of those cultural myths. it is in no standard I have. (MIL-STD-8, 66,73,82,94,09) Anyone else find it in the standards?

Jim,

I'm not really a fish guy, I think it's going to be some good old Alberta beef sirloins.

I'm the only customer in the butcher shop who specifies a profile tolerance for steaks instead of a thickness. I wouldn't want them to use calipers for the measurement, would I? ;^)

It's hard to get Alberta beef here without paying dearly with body parts. There's just such a pleasant difference between grazed beef & the feed lot beef we get here. Of course, if you did specify a thickness tolerance you'd still have perfect form @ MMC & a 2-point check to see they're not too thin. Enjoy one with a shot o' rye for me.
