I need to identify a cut/section plane and measuring field/s in a technical drawing for the inspection of internal porosity of an aluminum casting (destructive examination).
I've checked ISO, VDA, BDG, NADCA, etc., but none give an example of how this should be noted on technical drawings. Of...
Looking for some suggestions...
I am having difficulty defining the positional tolerance of features in a circular array. In the attached illustration (first angle projection), the tangent point of each bump to the red diameter must lie in a tolerance zone defined by two cylinders 0.2 apart...
What is the best way to control the size of a radius within the boundaries of a profile?
In the attached sketch, the nominal line in blue is flanked by the min and max profile boundaries. An undesirable condition is shown in pink. What controls are best utilized to ensure that the corner radius...
The product of discussion is a rectangular silicone slab with sealing surfaces around the perimeter and inside thru-holes positioned about the interior. The part is installed in a housing whose mating surface perimeter is porportionally smaller than the part's perimeter. This produces some...
I have a drawing with multiple pages. Datum A is defined as a feature of size on page 1. On page 2 we dimension another feature to the center plane of datum A. The center plane of datum A is represented by a centerline in this view, but because the centerline can be tied to multiple features...
Can anyone explain the difference between controlling the position of an FOS with a bi-directional tolerance vs. a 2 single segment feature control frame (non-diametric)? Both indicate direction and magnitude relative to specific datums. What are the benefits of one method over the other?
