How do you turn a part upside down and maintain yur past alignments? Is there a way to stitch things together or do you have to run 2 separate programs? Can't find anything in the hel file on this.
If the component is moved you will need a new alignment, as simple as that. No human or machine can flip a part and put it in EXACTLY the same place, so your error margin will be whatever the difference is between where the alignment was on the previous die (where the CMM thinks it should be going) and where the part actually is. Depends what your tolerances are as to whether you run the risk.
If, however, you do not need to link both sides of the component together, you can flip it, run a new alignment and carry on. As long as the results from the second side aren't calling from an alignment from the other side and are independent.
Personally I make one programme per side. So the operator turns it over, runs the next programme and it gets treated like a different component. It also means if the setters have issues with one side of the component they can just run the relevant programme rather than wait for the whole thing to finish. Whenever the component has to be touched, or if someone looks at it funny, I do a new alignment, no chances.
