Machining Symbol
Machining Symbol
(OP)
I've got a machining callout on a drawing that I haven't seen before. Wanted to see if I could get some help.
The callout is "60* T < on 3 1/4" Port Circle".
The * is for degrees.
I'm thinking that this just means total angle but haven't found anything to verify.

Probably should be Pitch or something though.

These are for a burner tip in a fired heater. Also, the port circle is correct as they are machined around the burner tip similar to a bolt circle.
The drawing we do have is from 1978.

Just kidding and you are right, that asking the customer is the BEST answer in many cases.
Don't make their ambiguous notation your problem.

Sadly OP hasn't responded to clarify so we may never know.
