We have a brand new FV1480 vertical with a Fanuc 18i-MB. I'm looking for a way to orient the spindle at 0, 90, 180 & 270 for a broaching operation that would replace an EDM outside process.
In the operators book listed in the M-codes is a M20. The description listed next to this is "Spindle Orientation The Angle (For ATLM tool length mesurement)". They give no description on how to program using this. Our sales rep is working to get an answer for us, but thought I'd throw it out here as well.
I've run some Fanuc machines with a spindle that you can orient to different angles, mainly for finish boring, and I've tried those codes.
One problem we may have is that our 4th axis on this machine rotates along X, but I had it's name set to "C" since we also have a multi-axis lathe that rotates it's rotary work on C. At the time it just made sense to me. But I'll change it back to A or B if needed.
Thanks!
