I have a print that is drawn in accordance with ASME Y14.5. On this part print there is an angle call out that states the nominal of the angle between 2 surfaces. There is no tollerance specified at the location of the dimension call out and there is no general tolerance specified anywhere on the print or in the title block that would specify the tollerance of an angle. In addition there is also no reference made to any other drawing standards that would define a tollerance that would apply to this call out.

When reviewing this issue i was told that there is a general tolleance specified for an angle within the ASME Y14.5 standard that is determined by the length from the apex of the angle that the 2 surfaces measure.

I have been through the standard more than once trying to figure out what this person is saying but i can find no general tollerance given to any angles based on distance from the apex anywhere with in the standard - other than a note about implied 90^ angles...

Am I missing something here - Please someone point me in the right direction.

First, if there's no tolerance given for the angle in question, the drawing isn't in accordance with Y14.5M. :D There is no such "implied" callout (except for 90° angles); either the angle is controlled with an angularlity feature control frame (6.6.2 in the standard) or directly as in section 2.2 of the standard. You should ask the person who told you about the "general" tolerance where to find the information, or ask the customer.

The person who told me about the "general" tollerance was the customer... he said that i would need to look it up in the ASME Y14.5 standard - when I found nothing i came here looking for help - thank you!

You'll need to educate your customer with what Jim Wynne stated.

Any sugestions as to how i go about doing that?

You say to the customer, "I've reviewed Y14.5M but I'm unable to find what you're referring to. Can you help?"

Any sugestions as to how i go about doing that?

Coleman,

Send the customer an email and "cut and paste" Jim Wynne's comments in it.

Jim would not object....:)

Not at all, but I could always spice it up a little...:tg:

Jim,

Your "spice" may be too hot for some...:D

Needed for some though...

I can not help You with ASME but what You are looking for ( tollerance given to any angles based on length and class) is stated on ISO 2768 part1
