Question

[tcovington]

This question isn't for a Mori, but a cnc lathe none the less. Its is for a Nakamura-Tome TW20 to be exact, I just chose this thread bc there seemed to be more views happening here and the simple fact there wasn't a NT thread. So my question is, I am doing a face grooving operation and did the programming via ESPRIT2016. I had it using a G74 Canned Cycle and it wouldn't read it correctly and instead of taking the necessary .018 peck it was attempting full depth. I went back and turned the canned cycle option off and left the tool path alone and it is running fine. could this be an instance where the technology is more advance than the controller? (Fanuc 16-TT) or what could be the issue here?

The canned cycle looked like this....

where is your line q and p for the groove definition?

[tcovington]

would that not be on line 14 of the code I posted that was generated via ESPRIT? The second G74 Line...

Correct. Just change line 13 to;
G74 R.06
