Hi pmarc, i did read further below the thread but it probably take time for me to digest.

thank you chez311 for the quick answer and the reference to the other thread...i downloaded the attachment =)

i believe this to be a silly question but i'm no expert and thus i just want to verify if this is the same or valid interpretation. There is a true position callout with a M modifier to datum A. i've always interpreted this where the feature (square slot) needs to be 'centered' to Datum A no...

Just wanted to say thank you all for your input =)

Thank you chez311, Yes this customer drawing is based off the ASME Y14.5-2009 standard. pmarc, Customer has a specific requirement for PPAP's, "All features on the drawing including basic dimensions shall be ballooned and listed on the Dimensional results report. Record the actual value of...

Hi all, When it comes to profile of surfaces i understand it to be a form and location tolerance of plus or minus half the value given. The attached image reflects a profile of surface to datum a and b of .005 which i believe it gives tolerances of +/-.0025 for all BASIC dimensions called...

Thanks for the reply C43n however i'm not sure what the part is for, i'm told its a fixture and that's about it. i thought the .730 would be coming off Datum C but again it's directly tied to it because the .730 is coming off a .787 +/-.005 base that ends up being Datum C. Again, i'm more...

Hi all, (Explanation of attached pdf: Top portion view of blueprint showing the datum's and area in question to those datum's, followed by images of a closer view of the questionable area plus my interpretation and finally on the 2nd page how i have been viewing it) i have a blueprint with a...

Hi All, This is a question more on measuring and wanted to get opinions on correct way to evaluate blueprint callout. A small diameter is placed at the angle of 45° at the end of a diametrically shaped part. i have measured this on a CMM and found that the values to be with the +/-.010...

Thank you all for your response. So it sounds like getting wall thickness based on blueprint isn't really possible (but this all started with customer asking about wall thickness') MKCSKI, thank you for your comment, "Because there are no datums with form control there is no motion control...

Thanks for the response Belanger; this is what the customers inspection indicated about that note: General notes on drawings stating that all diameters on a common centerline must runout .005 FIM is usually looking for coaxiality or location to one another. Straightness would be held per GD&T...

Thank you CheckerHater for the attachment. Based on the attachment (Fig. 6-2) saying, "the derived median line of the feature's actual local size must lie within a cylindrical tolerance zone". So then this is not a tolerance of a plus or minus .005 but total distance is .010 (see attached pdf...

Hi all, i'm confused, wonder if anyone can give me some guidance. There is a straightness callout for an inner diameter 1.303/1.305 of .010 (see attached pdf). i'm uncertain how to calculate this properly: an external feature (ID will act as an external feature) or internal (since its an ID)...

i don't mean to bug you but i just have one more situation with this part and i was wondering if you could clarify, based on your expertise. i found an article on the web written by you (Belanger) that indicated, "This means that there is a profile zone imposed around the entire perimeter of...

Hi Belanger, thank you for your answer. i just wanted to verify that you mean't "can't" instead of 'can' in the following sentence: "When it comes to angles, you can really translate the profile's linear tolerance of .010 to an angular tolerance". i just want to make sure because the...

here is another pdf of what i was curious about when it comes to tolerancing based on a profile of surface that is unilateral toward the outer portion of the part. thank you againhttp://files.engineering.com/getfile.aspx?folder=8b09ae17-baa8-4c47-997c-cad362babbd7&file=basic_question.pdf

Thanks for the reply, attached is an updated pdf showing where Datum A and B are (Datum A is the surface and B is just a diameter) Just in addition, sorry for the not so smart question, but when a profile of surface is an Unilateral Tolerance (Outside) does this make the BASIC dimensions +.010...

Hi All, Is it right or safe to just begin at an arbitrary point (based on basic point) that is marked at a specific distance and measure all other values based on this beginning point? Attached i have a blueprint for the part and i just want to make sure that i start measuring the part...

thanks dgallup, what you say makes sense, however in this case i see the term 'Flag Note' which is mentioned in Y14.100. Overall the purpose makes no sense to what we do here. The customer wants a portion to be alodined (labeled as a flag note) yet the entire part is already anodized...

Thanks for the response: tbuelna: i don't know why they use an asterisk on one sheet and then actually use a triangle on the actual blue print. i don't know if this has anything to do with the note indicating that drawing is to be interpreted according to 40M114. Maybe that has a better...
