Hello,
Today I saw a tolerance box for straightness which had a tolerance of .005/1 RFS.
I guess it means the part must be straight within .005 per inch. Does anyone know where in the ASME Y14.5 it allows this? I was unable to find it.
Hello,
Would anyone know if DOD-MIL-STD-100 drawing interpretation contains a reference to ASME Y14.5 or any other tolerancing and dimensioning standard?
Hello,
Does anyone know of a good reference text, standard, or instruction on how to draft and tolerance composite structures (eg. fiberglass panels, carbon fiber & resin etc...).
Hello,
Question about ASME Y14.5.
When a drawing is dimensioned to a sharp point of two intersecting surfaces or planes and there is a note on the drawing requiring break edges, how does the inspector know (from the ASME Y14.5) to inspect to the broken corner or the point in space where the...
When I specify a Parallelism and/or Angularity is it necessary to specify a distance(parallelism) or an angle(angularity)?
In my case I am locating two parts to each other which will be welded in place.
In the case of the parallelism there are two surfaces which require to be parallel, but...
If I have several chained dimensions, each defined with a basic dimension and a profile tolerance. Is the last dimension cumulative (sum of the basic dimensions + the worst case profiles) or can I just add all the basic dimensions in the chain and apply the profile once to the last edge?

Hello,
On a thick walled pipe there is a radial groove on the inside of the pipe. The groove is dimensioned by a radius and the depth is defined by a dimension outward from the inner diameter of the pipe to the top of the groove. The radius is larger than the dimension from the inner wall so the...
Hello,
Question about Min dimension in view.
On the drawing there are two concentric diameters shown in a cross section view. There is a Min dimension between the two diameters. The Min does not state ALL Around.
How would I know if the MIN is specified at that particular location or if it is...
Hello,
If I have a geometric control box(perpendicularity) located to "A", "B", & "C" where "A" is a surface(three point contact) and "B"(two point contact)is a diameter, and "C"(last datum 1 point contact) is a diameter.
How is the datum established if diameter "B" is not 90 deg to surface...
Would anyone know of a good book that explains how to calculate the contruibution of the MMC on second and third datum boxes?
I have a True Position where datum A is the flatt surface and datum B and datum C have the M behind them.
I understand that these would establish a functional gauge to...
Hello,
Is there any standard to determine the glide ratio of a bicycle? I was looking for a standard which would be like: a bike loaded with rated load allowed to glide down an angle slope of a certain surface roughness and measuring the distance the bike went.

Does anyone know of a reference which describes the amount of magnetic force that can be obtained from a wire related to the gauge of wire and amount of current/voltage passing through it?

I am having difficulty understanding a section of GD&T.
I have a flanged pipe with a boss on the side. The hole in the boss is located with a basic dimension and a true position in which Datum C is a hole in the flange at an angle relative to the top hole.
Because the size of the C datum is...
I am stacking up a series of axial dimensions and have encountered a difficulty. Any help would be appreciated.
There are two cones (inside and outside cone) of the same basic angle which will be assembled together. Each cone has a basic angle, and a basic dimension from a vertical face to a...
When I use Catia R10 drafting I get and error message that says: "A Check of Active Document Will be Done". After this message appears my computer stalls and eventually gives a timed out error which cancels my Catia session.
Would anyone know what causes this error?
Thx
Robert
