Ralph;

   Yes, that could be done like other responses that you already received.
    But keep in mind that some amount of time will be spent by " adjusting "
the machine program when all the components arrive, I will give you some
points that contributes for this delay.

    Components angle most of time is wrong because a 0 degree for a
component in CAD not always is the same 0 degree orientation for placement
machines

    Some components need size adjusts in the machine library in order to be
recognized by vision system

    Some feeders has to be changed because some parts can come in reels or
stick or trays and you will only known when the components arrive.

    Cycle time could be affected after adjusting the machine with the
components and then new line balancing must be done in order to get higher
troughput with better machine optimization.

    This list could be enlarged with specific cases but my intention is just
advice you that you can reduce the time, but not as much as you could be
thought.

I hope this help
