Quick answer before I go out. Peck Tapping breaks the chip otherwise they can break taps. Eg tap m6 down 30mm you might break it. But do it in two bites you should be sweet and rpm is 400.
If I somehow work out how to know if g33.1 (rigid Tapping is active) and export that to a python script. Then I can change my spindle acceralation briefly and tap at 1000rpm with almost no over shoot. The spindle Vfd can reverse in 120degrees currently at 1500rpm But that will take some coding I think. I can change acceralation on the fly with custom m codes and halcmd currently but need to to set it up to automatically change back and forth if rigid Tapping is active On Tue, Aug 10, 2021, 11:50 AM John Dammeyer <[email protected]> wrote: > Impressive.
