    System variables for Fanuc Control

    Hello all,We have a job that requires changing new insert in the middle of the cane cycle (Rough cut). Sometimes the operator forgets to change it so I want to write a macro to stop the machine and ask the operator to replace a new insert in the middle of rough cut cane cycle.Is there a system variable to record the current position of X or some thing so that I can signal to stop the machine and popup a msg? I know #3006=1 will popup a msg ....Is there a system variable to record the reset button when it is activated?I have a mori seiki TL-40.Thanks for your help

    First, this is the Okuma forum, so the depth and breadth of replies may be lacking.
    Next, there is a system variable to read the current position of any axis at the moment the line of code is read, but not necessarily at the moment the reset is hit. The machine simply isn't tracking that to my knowledge. Even an Okuma tracks previously executed line, not position when reset. So during a LAP cycle, it tracks what it's last completed sequence is, but not the position within the individual line or movement.
    Lastly, if you have a job that requires an insert change mid canned cycle, you're probably better served to run two canned cycles. Keep the same shape, but add a finish stock allowance on the first one that divides the roughing in half, then after that cycle completes flag the machine as needing an insert change. However, if I were you, I'd probably try to get a second tool mounted and figure out how to keep the machine running for one part and not stopping halfway through.

    Good luck and maybe post this in the Mori-Seiki forum to see what they can come up with.

    hi nodo, if the operator forgots, then protect the machine, by using load monitor, and, when it stops, execute a mid-cycle restart / kindly

    Thanks for your response. I like the idea of having a second tool and keeping the machine running.
