Are you an Engineering professional? To control the dowels equivalently with the 94′ standard in this case one would have to use two single segment position controls rather than copying the former composite FCF.

If so where is an inexpensive place to purchase the specification? It wasn’t defined very well, and what’s in the ed. Delete comment or cancel. The only asms a big problem occurs is when someone who knows how to interpret the composite callout but has no history with the intended control Do you really want to delete this prezi?

Present to your audience Start remote presentation. Tolerances for the profile symbols are equal bilateral unless otherwise specified, and for the position symbol tolerances are always equal bilateral. Inspection went hog wild, however, and started inspecting all of them with magnification and cast molds, looking for flat spots, radii reversals and tangental mismatch, and writing a lot of rejections.

It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. Join your peers on the Internet’s largest technical engineering professional community.

However, long term you’ll hit the problem you have now sooner. A datum feature is a physical feature of a part identified by a datum feature symbol and corresponding datum feature trianglee.

Their twist is to NOT use any positional tolerance callouts as they have had too much mis-intrepretings from it’s initial use. It’s is perfectly legitimate for old drawings to still call up the old spec.

As tight of tolerances that these designs require – optics design – I wonder how it could have been done RIGHT all these years without consistent datum assme. One of our programs added a standard drawing note that “All radii be CR unless otherwise specified. Same is true for Concentricity.
