Hi, We are using ASME Y14.5-2009. This is a MIM part (mold). Our Design department's final checker is a Manufacturing Enginneer. He has REDLINED a part that I don't fully agree with, but I could be wrong. Please HELP. The base of this part is critical to fit. Two opposite sides are angled...

ASME Y14.5-2009. I am checking a small casting, product design drawing. The part is about 6 x .75 x 2.5 inches. The tooling/manufacturing engineer wants datum A's three target areas to be on 3 different surfaces of the casted part. Datum B's two targets are on one surface and C is...

Hello, We use ASME Y14.5-2009. We have two different opinions here. Is a 90 degree angle ever dimensioned? There is an arc with a line tangent to that arc at 25 degrees from the vertical. There is another line on the otherside of the arc, tangent to that arc, which is 25 degrees from the...

Hi, I would appreciate your help. ASME Y14.5-2009, MATL: 302 SS .040 THK, OVERALL SIZE IN INCHES: 4.000 X .075 & .325 X .040. 2 Bends. The engineer has DATUMS A, B, & C. No FCF showing any relationship with B to A and none with C back to A & B. He does have one bend with profile of a...

Hi, ASME Y14.5-2009. Profile of a surface with no datum refs, is it only the surface itself that is basic, not the dimensions locating the surface?

When 2 surfaces are to determine one datum plane, how is it called out on a design drawing? The two surfaces are in line, but interrupted by a rib (wall). Could I put a Datum A Symbol with "2X" or "2 SURFACES". Datum targets? Is there more than one solution. I understand an extension line is...

Why would someone use PROFILE OF A LINE, on a surface, as opposed to PROFILE OF A SURACE?

I have a spring with one leg horizontal then .072 BR angling down 15 degrees. On the paper plan or top view, the two legs need to be in line to each other within .007. Should I use profile or parallel or what? No datums.
