Posting SFM with G96
Posting SFM with G96
(OP)
I'm new to post builder and i'm try to get SFM to post out with G96 but only seem to get spindle speed. If I switch to SFM in part file I can get it but then I lose my G97S##M03 in program. Any help.





RE: Posting SFM with G96
You can't get both at the same time if that'w what your loking for. The machine will only read one.
Make sure the spindle commands are set correctly in your post. You may need to creat a lathe control operation to set the initial speed to rpm prior to moving, you can also set a approach marker in the machine control part of the operation and then an extra spindle speed to set your SFM.
You may need to force the G96/G97 output so it will change.

N19 ( RGH-FACE-FRONT-0.005-STK )
N20 G54
N21 M41
N22 T0101
N23 G97 S183 M03 <----starts spindle in RPM
N24 G50 S450 <----G50 is "max RPM" on this machine
N25 G96 S500 M03 <----changes to surface mode
N26 G00 M08
N27 G00 X10.462 Z2.165
There is nothing really special to do in postbuilder.
Make sure you have "PB_CMD_spindle_sfm_prestart" and "PB_CMD_output_spindle" custom commands in the Initial and First move events.

Good Luck,
