What would be your reaction to a drawing showing a prismatic feature on a part, comparable to those that are found on V-blocks, a phantom line circle tangent to the 2 angled surfaces of the prism, the circle specified with a basic diameter, and a datum feature symbol associated with the phantom...
1. Fig 4-42: why are all the datum target areas symbols used with dashed radial lines? For datum A, I understand that it means that the designated areas are on the bottom (hidden) side of the hood. But what do the dashed lines mean for datum areas B1, B2, and C1?
2. Para. 4.20 - Restrained...
My first question is - according to ASME Y14.5 2009, how would you classify the cylindrical interrupted surface of diameter 55 and the width 52 in the following sketch?
Are they:
- Regular features of size (with interruptions)?
- Irregular features of size type A? (Or maybe even B?)
My...
Hi all, it's been a while, hope you all are doing well.
thread1103-297880 is where I learned about the problematicity of applying Position to tapered features. Dean and pmarc noted that where a position tolerance is applied to a size dimension specified on the end face of a cone, as it is done...
What are the opinions on the following schemes?
1. Angularity control referencing 2 datums in the FCF, when the basic angle is specified between the controlled face and the secondary datum. The primary and the secondary datums are perpendicular to each other.
2. Parallelism control referencing...
As requested by pmarc, I'd like to continue here the discussion about CDRF concept, which started to take over thread1103-441690 , in order to allow it to get back to it's initial topic. For those who were not involved but hopefully also interested - we were discussing the difference between a...
