Looping alignments

ethanb
Im currently writing a program to inspect 4 parts on a fixture. Im looking for some help with creating a loop that has multiple alignments to reference to, but only loops 1 measurement routine (hole locations, planes, etc) and updates those theoretical locations based on which part is being measured. I have a input comment to the operator to say how many parts are being inspected, and made an assignment to that value. That value is then driving how many times the loop will cycle through. I just cant figure out how to make different alignments active, and update the features theoretical values.

  • When you do a Loopty-Loop you need an alignment inside the loop that will change with the next part, so in other words,

    Manual Alignment

    DCC/MODE

    LOOP Start Moving in X or Y Direction

    DCC Alignment

    Program

    (Maybe a Print Command)

    LOOP/END

    Im not very far along in trying to get this to work... Disregard the last circle, as i was going to attempt to get that circle to loop to the 4 parts after i define the 4 separate alignments. Aside from that - hopefully the code is helpful, see below:

    The 4 parts dont move the same distance each time the loop needs to repeat. Currently the fixture layout would start at the first parts alignment, then the next alignment (part 2) coordinate deviation would be x 0, y 4.75, z 0. Then after that, the 3rd part alignment would go from the 2nd part to x 4.06, y 0, z zero. 4th part alignment would go from part 3 x 0, y -4.75, z 0. Hope all that gibberish makes a little sense

    Thank you for the reply.
