If you perform laser cutting or marking in your facility you’ll know that while the machine might be very repeatable, the blanks and the fixturing are less so. This means that the target will be in a slightly different place every time.
One way to deal with this is to spend more money on higher precision blanks, and yet more money on better tooling for repeatable blank location. However, a smarter alternative might be to give the laser “eyes” so it can decide exactly where to put the beam.
That’s what Worldwide Laser of Gilbert, Arizona have done with their laser vision system. Machine vision is used to locate the target edges or region. These coordinates are then input to the machine controller which drives the laser to the required location. Seems like an elegant solution to the problem.
