I'm sorry i was omitting general words like F and S, I was focusing on those words more specific to the canned cycle, and in particular U and W which i was already told would not work out too well, since they were used for the second turret motion. Based on the use i see, i will likely omit reading an S on the G71/G72 line in EMC2, it serves no purpose. I will not read any feedrate inside the code block defined either, since i will not worry about implementing a now superfluous G70 finishing cycle. It is confusing enough to end up at the beginning of the program if you reset a Fanuc inside the G70, i will not forward port this nonsense to EMC2 ;) (I explained enough confused machinists/operators why their "code suddenly changed" :P ) I guess i will summarize the G71 not only on a which word does what basis, but also detail the intended behaviour. > > and optionally > > I Distance and direction of rough semifinishing in X > K Distance and direction of rough semifinishing in Z > > With those additions it's as per obsolete Fanuc controls like 6T, 10T, > 11T, 15T > > Now if you want to leave the eighties, current controls like 0T, 16T, > 18T, 20T, 21T > > all use a two line format > > G71 U.

One note, think of feedrate and speed not in such hard terms, F and S should adhere to G94/G95 and G96/G97 respectively.
