[Cl...] Posted July 23, 2019 Share Posted July 23, 2019 I have two surfaces (Planes) that are 90° from each other. These two surfaces are called out together on the print as a surface profile. I'm scanning (CWS light) 2d curves on each plane surface, and recalling them into a 3d curve for evaluation. I know I said that the callout is surface profile, but if I try to use a FFS for evaluation it fails. The customer is ok with this approach. The problem is that my results won't pass a type 1 GRR. Any suggestions. Link to comment Share on other sites More sharing options...
[Me...] Posted July 23, 2019 Share Posted July 23, 2019 What is the callout? If the surfaces are both fully constrained (6 DOF) you can just do a profile of each plane separately. If they are tied together and have something like profile with no Datums (Form only) then you will probably need to do some sort of Best Fit Alignment of the planes, allowing translation/rotation as applicable, and then re-measure them to that alignment.

[Cl...] Posted July 23, 2019 Author Share Posted July 23, 2019 They are fully constrained. The part is a cylinder, chucked in the O-inspect rotary facing Y- The surfaces (4 of them) are two vertical planes and two horizontal planes 90 deg from one another on the X+ & X- sides of the OD (Datum -A-) (surface profile .003 to -A-), but it's called out as 2x. Per the drawing I need to report SP twice. Link to comment Share on other sites More sharing options...
