Rotational Pattern of Irregular Features
pmarc, Again thanks for your time and attention. In MY haste, I think I confused datums A and B. I had it in mind to make the slots and vanes perpendicular to what is now called datum B and D respectively. But that's a minor point. The coaxially between A and C is important for the sake of...- ruscag

Rotational Pattern of Irregular Features
pmarc, Thanks for the reply! I thought I'd need composite since the two parts will be manufactured by two different shops. Also to keep datum A and datum C as concentric as possible I wanted to locate the pattern from the bores. Then the two are welded, finished machined and mounted on the...- ruscag

Rotational Pattern of Irregular Features
I need to define two patterns of shapes (slot and vane) that fit together for welding. The engineer wants to keep the clearance to a minimum. After doing some homework, I thought to use composite profile of surface tolerance to define a PLTZF and FRTZF framework. My problem is I don't know how...- ruscag
