Please see the image attached. This would be a cross section of the cylindrical part.
I am trying to figure out the best way define the 'parallelism' between 3 diameters of a part, more specifically defining the tilt of the middle diameter to datums A-B. The initial thought was to use a total...
If I have a part (a cube for example) which has the primary 'A' datum on the bottom surface (B and C datums on faces perpendicular to it), and a hole pattern on one of the surfaces perpendicular to A. In a composite frame I would have the top to datums ABC, then would the FRTZF be only to A or...
The raw material is a 5m long aluminum extrusion that we put through an extrusion milling center, about 100 of these pieces come out of 1 piece of raw material. The front and back faces are extruded material and not machined, the outer profile and holes are all that is machined.
The...
In that case how is the position of the large hole controlled. If it was a flat plate, it makes sense, but it needs to be in a certain position relative to the step down. Hence my thought of changing the ref dim to a toleranced dimension to the step.
The stock is just a reference, I agree its...
We are making parts out of extruded stock and trying to redo the prints with GDT.
The part is machined all around and we want to use 2 holes as the secondary and tertiary datums.
However it is not a flat plate as usually shown in the ASME standard, and the hole (datum) needs to be controlled to...
