Composite position on non-patterned features
Composite position on non-patterned features
(OP)
I have a threaded gland with a flange and a bore. I am trying to position the threads, I want the primary datum to be the flange and the secondary to be the bore. I want to then refine the orientation to the flange.
I want to use a composte position, but I am not sure if I can beacuse the feature isn't a pattern.
Is it legal to use composite position control on a non-patterened feature?

RE: Composite position on non-patterned features
First frame will loosely locate to [A] and [B], than second will tighten location to [A].
Haven't seen it done on threads (what are you locating; MD, PD?). So, I am really curious what others have to say.

It is the PD, we usually put an MMC modifier on the position so a functional gauge can be used.

|POS|Ø.010(M)|A|B(M) and refine by
|PERP|Ø.005(M)|A
