I am currently working with a product that has a tapered blind hole. The taper is called out by two diameter limit dimensions one at the top and one at the bottom as shown in the top picture.
The problem is that, IMHO, this dimensioning scheme doesn't give any position tolerance, doesn't well define how the taper of the hole should look and is difficult to gage.
Two options were developed as shown in the bottom picture. But I don't know if they are proper to address the three concerns stated above. The top option on attachment looks like it gives no positional tolerance compared to the ID. I understand the intent of the bottom option but I don't know if it is correctly using the standards. Maybe there is a third option that someone sees for this. Thanks in advance for any assistance and please let me know if you have any questions.
