Equate Alignment program problem

I have a part program, i have successfully written it to where i can flip the part, and equate the alignment, all works well, until the next part is ready to be measured. I cannot get the Dmis to go back to the startup alignment at the beginning of the program. I am forced to do a manual alignment for each part. Normally, i manually align the part once, run it through, then the next time i turn off the manual alignment features and run it over and over again letting the dcc alignment take over.

This program will not do that, everytime i start the program over again without the manual alignment features selected, it thinks that the probe head is still on the negative side of the Z axis, which is not true. I don't know why it is not looking at the startup alignment that should tell the program that the probe head is in the space relative to the machine and not the part.

any thoughts? i hope i have just missed something stupid here....

  • I figured it out, at the very end of the program you just have to equate back to the original alignment, and it will set things right.

    Thanks guys/gals!

    Hi Sam,

    Would you mind expanding on this a little bit? I use Equate Align a lot but I was using a manual machine before and never had the luxury of NOT manually aligning for a second piece. For everyone's benefit...


    I create my first orientation alignments A1 - A4 (two manual then two DCC aligns) and measure what I can.

    I then do "recall:startup", flip/rotate part, and do A5 - A8 (two manual, two DCC in new orientation).

    A8 must be identical to A4 relative to the part, do an equate alignment A8 to A4, and measure the rest of the part.


    Problem is, on second run, manual alignments are not right anymore so DCC goes wherever, as though the program still thinks it's in the equated orientation. Here is the question I have. What aligns do you use to equate back? Does this work to unmark the second set of manual alignments after the change (A5 & A6)?

    Thanks,
    Vernon.
