Hey, can you peck with a G82. I want to use the dwell (P) address for chamfering, but was wondering if I can use a Q address and peck too. I was under the impression that the G82 format doesn't include a Q address. Thanks |

| Fanuc controls. I typically counter sink using G73, a slow speed of about S350, a slow feed of about F1.5, and small peck of about Q.015. Those are my go to parameters at the moment and they usually work fine with a sharp tool. A guy at work was struggling getting a descent counter sink the other day, and some other guys were telling him to add a dwell of about P1000 or so, hence the G82 cycle. I was convinced his problems were related to his setup, but thats neither here nor there. Anyway, I made the point that you can't peck with a G82, and other folks thought you could. So just for ghits and siggles, I added a Q address to a G82 cycle and ran it. It didn't alarm out and ran, but to be honest with you I couldn't tell if it was pecking or not. I sould have used a larger peck to experiment with, and overrode the feed to slow it down enough to seed, but didn't have time to mess with it. So, the G82 cycle ran with a Q address, but I'm still not certain it pecked. And there ya' have it. |

| My guess would be that it did not peck. The G82 line will except the Q value without alarm but may not run it pecking. I do this in my macros all the time. I allow the operator to select the drill cycle that they want to use and in the macro line there is a Q value. If he uses a peck he can set the Q. If he chooses to not peck by using a G82 or 81 then he just sets Q0. Stevo |

| Yup. I was pretty darn sure watching the operation that I wasn't seeing any pecking going on. So, I have officially established to my own satifaction that G82 don't peck. But Caprirs may have inadvertantly raised the flip side of my question. I'm thinking this is a typo:
Because G73/G83 don't dwell, right? |
