Please see the attached drawing that I quickly made. I am working on a component with similar geometry and I would like some feedback on a few questions.
1. The position of the Ø.750 hole references primary datum C and secondary datum B. This datum reference frame fully constrains all 6 degrees...
Everywhere I've seen states that the wavelength of the filter is equal to the sampling length. Is this a firm requirement? We are measuring spherical surfaces and we can't quite get the amount of surface measured that we would need to use the filter that matches the roughness requirement. My...
I have attached a basic image of the situation that I am faced with. There is a sphere and a swept (toroidal) radius. The distance from the sphere center to the radius center has a +/- tolerance. The size of the radius has a +/- tolerance. I'd like to convert this to a profile tolerance, if...
I have attached an image of a particular situation that I am wondering about. As can be seen, there is a profile of a surface tolerance on a small arc with respect to datum features B and A. My question is in the validity of the current dimensioning scheme.
The profile is from point X to point...
I just saw that ASME put up the new math standard on their site and they are accepting preorders. I have been looking forward to the release and I know some others on here have been. The website appears to have a release date of 10/02/2020 and there doesn’t appear to be a PDF option.
Y14.5.1-2019
I have attached a very crude drawing of a simple part. There are two datum planes (A and D) and two datum cylinders (B and C). Let's assume that I wish to assign a positional tolerance on datum C, with datum references A and B (applied at MMB). The question is this: What is the size of the MMB...
I have a print that has a composite position tolerance on one feature of size. Y14.5-2018 contains section 10.5 titled "Pattern Location" that goes on to discuss composite positional tolerancing and multiple single segment positional tolerancing.
Is it valid to have a composite positional...
We have several blueprints that call out Position tolerances on the I.D. bore of a ball in the following way:
Primary datum reference A - Planar surface with normal vector along Z
Secondary datum reference B - Cylindrical feature with axis along X
There is a ball that is free to rotate within...
I have attached a very basic image of a part that I am dealing with. Datum feature C is a cylinder, datum feature D is a cylinder, and datum feature E is a cylinder. These three cylinders are mutually orthogonal.
(1) Datum feature D has a Straightness tolerance at MMC.
(2) Datum feature C has a...
I have attached a stripped down print of a part - A cube with two holes in it. Top face is datum A, Center hole is datum B, Side face is datum C.
The question that I have comes down to the theory behind the dimensioning I guess. I have listed three datum reference frames for a Positional...
Y14.5.1 Public Review Draft - Does anybody have a digital copy that they can send my way? I heard on here that it was a free draft when it was released, and I'd like to prepare for the upcoming release.
Thanks in advance.

I am interested in taking a look at ASME Y14.5.1, but I've seen others on here saying it is not quite useful. I would like to attempt to ask management to purchase it, as I have a degree in mathematics and it may assist me with CMM programming. Can anyone here tell me the extent of the math that...
