Basisausrichtung(Messelemente)/ RPS Ausrichtung

[[Re...]]

Hallo zusammen,

wie seht ihr das?

1.Ich habe ein Bauteil und mache an diesem Bauteil die Ausrichtung nach den Messelementen und erstelle das Basissystem

2.An dem gleichen Bauteil mache ich eine RPS Ausrichtung.

Welche Ausrichtung ist nach eurer Meinung stabiler?

Ich Frage, da ich selbst mit RPS Ausrichtung zu wenig Erfahrung habe.

 

Danke

Well it depends on your features and a drawing.

If you customer want's to evaluate against RPS, then use RPS.

Base system is not following ISO/ASME rules of making alignment, so don't rely on it. It's good to have a good, big and reliable base alignment, but it's just for locating measured features.
You will see it if you had a long or warped part.

RPS is literally using about 6 points which are taking all freedom - so in this way you are good to go.

It's depends how precise your element strategy is are and what are your RPS and how are they distributed

Plane / Line / Point is a general idea of setting up the alignment and it's correct as long as it matches the drawing 

If your results aren't repeatable enough, you might want to try iterative alignment
