M-code for Chuck Clamp/Unclamp
Hey there. I have a leadwell LTC-15 with a Fanuc-OT controller. I am trying to use a new barpuller we have here at the shop, and im having problems clamping and unclamping the chuck during my program, to use the bar puller. I have a book with an M-Code list in it, however it is for a Haas lathe, and the numbers don't quite match what they actually do. Im lookin for either the correct code, or an eduated guess which 2 M-codes they are; as long as they are in pairs. I was messing around with random M codes, and it took me 10 minutes to get my turret to index back in. LOL. Thanks a lot.
Chuck Open ... No Cycle Start
Hi ... if you're doing this in Single Block like for a test ... once the chuck is open the Cycle Start will not work as it is a safety ... you know, the machine won't start with the chuck open. In full auto ... this would not happen since the Cycle Start doesn't need to be pressed and will work fine.
To test, you can do a couple of things :
(1) Once the chuck is open ... close the chuck manually rather then waiting for the M code and then continue with the program.
(2) Once the chuck is open ... change the ID CLAMP or OD CLAMP option button / switch to the other ... that will make the chuck "think" it is closed and the Cycle Start will work.
Hope this helps ...

There may be a parameter to inhibit motion with the chuck open.
Here is some bar pull code for a Daewoo with Fanuc 0t.
Some machines may need dwell after chuck open and close.
