    Default Bar Feed Macro Program for Mori

    Hello all...

    I recently installed a LNS quick servo bar feed on my Mori ZL-150S. I am knew to bar feed jobs and macro programming as well. I know there are hundreds of posts about bar feed macros on here, but I can't seem to find one that fits my scenario. Plus understanding the Macros is a challenge for a newby. what I am trying to do after the sub spindle finisheds the 12th part is load a new bar and start another program loop. Basically the LNS loads the bar into the top-cut position, and after that the lathe makes 12 parts from the loaded bar. The lathe does it's own bar pull and part off with the sub spindle. I would like the program to loop 12 times and then call up a bar load with an M70. After the LNS loads the new bar start a new loop. The top-cut routine only runs once at the beginning of the main program.

    Any sample programs would be greatly appreciated.

    you may be able to program in a work counter that uses an IF/GOTO to jump it to a sequence to make the bar loader push after the 12th part. THen the loader will hit the end of bar position and automatically go in to a new bar load sequence. for instance

    (End of Part 12)

    iIF V1=12 GOTO666

    N666
    (push bar)


    Or how most people run loaders is they use the loader to push the bar to a bump stop every new part and when it hit the end of bar position it automatically lads a new bar. This way it doesn't matter if you have the same length bars every time either.

    Since your using a sub to pull material, the LNS should be set for bar check. It should count the chuck open/close and then you set it to check every Xx parts, once the LNS detects short bar, it should auto re-load, triggering usually a block skip or block skip 2 to tell the machine to top cut program. Obviously macros can work the same way, however this functionality is built in.
