true position question

[jozey]

When I report true position in Xact and compare to legacy my position is out of tolerance the same amount which is a crazy number....but when I report the location of the diameter i am within .0015 X Y.... is there a chance pcdmis is.... calculating position incorrectly because .050 seems a bit much.. Thank you

[KIRBSTER269]

Lets see some pics of these results, are your X and Y's the same? Blind leading the blind

[jozey]

the x and y are the same when I report xact and legacy... but when use location they are very close..

i dont know how to post pictures im sorry..

In the past when I had this issue it was because of my alignment... in this instance i am confident it is not my alignment..

[bfire85]

What are your datums? Is your legacy alignment datums and the datums you define for Xact the same?

Post some code?

[jozey]

how do you post code again?

theres more but thats all the code up to my dcc alignment,,,, thank you for cleaning that up for me

[JEFMAN]

cyl_datum_h, pln_datum_f and lin_datum_e have the same theo vector, and pln and cyl have very close theo coordinates.
Without seeing the print, I can be wrong, but I think it's strange.
I would check differences between datums references and alignment.

my part is basically a cross thats slanted..... DATUM H is the right side bore of the cross.... DATUM F is the face of DATUM H... and DATUM E is the other side of the cross through to datum H.....Hope this makes sense.....

hopefully this helps clarify...to show all the datums.... C and D are strange so I used the bore for C and constructed intersection points to construct datum D

How log is the bore for C ? Is that a casting ? If C is really short I would consider using the larger OD surface for leveling and then 0.000 on the bore for x -y or z. Depending on machine process I do that for a bunch of parts we do. Bore is really short be we do concentric bore on opposite end of part and then hold it from both ends, like turning between centers. I make a compound datum from both bores. Only 1 end is the print datum but its so short it alway told me my feaures along the length were" wandering" off the part. Indicator would tell me I am withing .0005. Change to this datum structure the CMM matched the indicator flawlessly. Yeah, I know the print says.....blah blah
