I think your right in that the best place to have it would have been on the process/"make from this" drawing as you have it called out. With the "make from this" drawing in process and the finished drawing clarified I think the machinists and I will split the pizza and each send you a slice.
ewh,
I agree and apologize to you and Mike. Effectively the part is blanked on a lathe and the edge that gets this chamfer is there only to remove the burr left from the cutoff process. It is not intended to provide your typical thread lead in as the design intent is to have no chamfer after...
Thank you Mike and PowerHound. I completely agree with your suggestions but to the root question, do you agree that the origianl call out starts from the cross section of the hole?
Of course and that would be a better way to clarify the design intent, however the question of where the original (.015 x 45 deg) measurment starts from remains.
Is the chamfer call out .015 x 45 (degree symbol)on an internal threaded hole measured from the diameter of the cylindrical hole feature or the major diameter of the thread?
Example: I have a 3/8-24 UNF-2B threaded hole and I want a .015+/-.005 chamfer on the edges of the letter Q (.332)...
