1 alignment, 2 parts?

I've got 2 parts, mirrored in Y, on one fixture. The fixture has 3 tooling balls, each with 2 sets of coordinates, one set for each part. Is there a way for me to write both parts into one program without having to pick up the tooling balls more than once?

I do this all the time, but you will have to do two DCC alignments, how you get to that point is really up to you.

I personally do a manual alignment using the top of the fixture base, an edge of the fixture base, and one of the tooling balls that has values for both parts. Level (plane), rotate (line, edge) and origin to the ball for the LH, then go into DCC and measure the actual part locators for the LH, save that as an external alignment, then do a new Level, rotate, origin alignment for the RH, using the same manual features, still in DCC, and then measure the actual part locators for the RH, save that as an external alignment. Then simply recall those alignments in the check program(s). IF the parts truly are symmetrical, you only have to write ONE program (I always start with the LH), then mirror it for the RH, change the alignment recall, and you are good to go.
