*How to do a Final Pass W/O programming

[chip6990]

I know there is a feature on a Haas, but I am not sure on a Fanuc O-T(Ecoca SJ-35 CNC Lathe)

is there a way to program the "final path" w/o programming all the rough passes?

I'm a newb but couldn't you just re-run the program from the start of the finish pass in the program?

what i am saying is, there "should be a Parameter or G-code that will allow me to program the final/finish pass w/o programming all the rough passes. in other words, this "feature" would leave enough meat on it to do the final pass. i just tell it how big the original size of the part is and program the final pass. and it calculates the rest.

G71 = Rough turning similar to Haas
G70 = Finish turning similar to Haas

I believe your talking about a G73... kind of like a rough finish pass where it stays what ever amount you designate... sort of like a G71 as far as programming it..
