Lathe Gcode Cycles

Post by tmday7 » Mon Apr 01, 2019 2:23 pm

Tom,
Is there any plans to add Fanuc Gcode cycles to KMCNC lathe?
Like these most common ones ...
G71 http://www.helmancnc.com/fanuc-g71-turning-cycle/
G72 http://www.helmancnc.com/cnc-fanuc-g72- ... le-facing/
G76 http://www.helmancnc.com/cnc-fanuc-g76-threading-cycle/

Thanks,
Troy

Hi Troy,

I've been looking at this. I suspect G76 would be most useful. Would you be willing to debug and test? Do you think the Mach3 style would be more standard?

Hi Tom,
Yes, Mach3 version looks real nice for programming at machine, which is why iam asking for the Gcode cycles.Dont know how easily it would be implemented in a CAM post processor. Either way iam willing to test code. :)

Another cycle that would be just as useful if not more than G76 is a turning roughing cycle like the G71.

Thanks,
Troy

Haas has a simplified G71 thats just one line. Ive used this on a Haas lathe and works just fine.
