help wanted! how i can flip my part and have the program stay as the orginal

[francisco_cmm]

I have a part with 2 face call out. i finish programing one face but now need to flip the part and program the other side. my question is how can i flip the part on pcdmis and change my Z with out anything moving. each time i try to flip or rotate my z and everything i program moves. i don't want to create two different programs because on the second face, holes call for tp and the datums are located in the first face. i cant set this part on a fixture where i can have asses to all faces in one program on the cmm.

I'm not sure if it'll work in your situation, but sounds like an equate alignment might be helpful

[francisco_cmm]

i tried to do a equate but it fail.

[bherrin]

It took me a couple tries at first too, what I would do is measure and create an alignment of level / trans z to -A-, Rotate to -E-, and trans X & Y to -B-. measure the other feature on that left view that you need to. Then flip the part, re measure -A-, -B-, and -E-, and reconstruct the alignment EXACTLY as the first alignment. then add in the 'EQUATE/NEW_ALIGNMENT, TO ALIGNMENT, OLD_ALIGNMENT'. You may have to run it through a time or two to sort the Graphic Display Window out.

Are you trying to transform the CAD model? Or are you selecting new features and making a new alignment?

[francisco_cmm]

I am trying to keep the same alignment, then flipping the part to its other face, make another alignment then i create Equate but then it flips everything on me.

My first alignment is to the view on the left side. now i am trying to flip the part so that view on the righ side is facing up on Z+ and the view on the left will be on the Z-

My go to was to bring in 2 CADs. 1 face up and 1 face down ( or however will work). I pretty much do a manual alignment/ DCC and check everything I can. Operator comment to " flip part over " and then start with another manual alignment/ DCC. I would then do the best I can to duplicate the exact same alignment as the 1st side. Its not always easy and its not always possible. Its really 2 programs in 1. Your print and tol. will dictate if this process will work for you or not. I have no clue how to transform the CAD in DMIS and everything I do with CAD is done in solidworks as an assembly and then saved a single IGES.

If it will allow me, where I can square the part in the same height as the first setup, I'll take my second model and align it the first model at 180° and go straight into a DCC alignment. and hide my first model while doing second side programming.

We use the rayco quick fixturing so I do use 2 manual alignments. I will only the manuals on the 1st part after I build the inspection plate and then after that Its unmarked and it will go straight to DCC so theres not alot of manual work.

[Matthew D. Hoedeman]

I would set it 'on edge' and check it that way. no problem reaching everything with 1 setup and 1 alignment, like the middle view, part 'on edge' not on flat.

[francisco_cmm]

Matthew could you explain to me what you mean by "on Edge". I did try to figure out away with a fixture and tried to get creative but I ran out of ideas and this part is way to heavy to be moving around a lot
