    5/16" (8mm) Cutting Issues

    Hello!

    I recently was put in charge of programming our 4k Mitsubishi Fiber laser and we are currently running into an issue with cutting parts. We have the parameters set to fully cut the parts, but occasionally the part will not cut all the way in a random spot causing us to lose roughly 20% of parts. While they are small parts it still is frustrating as I would like to utilize lights out with them as there is a massive quantity needed. Here is a list of things we have troubleshot to isolate the issues.

    - Lead in was perfectly centered
    - Mode shot came back clean
    - Programmed for the machine to skip around on the program to minimize heat
    - Checked nozzle size and roundness
    - Going to try pre-piercing on our next run to see if that helps minimize heat as I think this is the issue we are running into.

    I'll attach pictures of our parameters as well as what the part is doing when cutting. Anything suggested will be appreciated as this is becoming a thorn in our side.

    Thanks in advance!

    Attached the wrong picture for the cut out. Here's the backside of the part.
