slla? never heard of it. How about the model of the control?
Remove 333 to reply. Randy
Mori Seiki SL1a?
Mori Seiki, could be either Fanuc or General Electric
The methodology of the left has always been:
While you might get the code you want here I'd say if you want something done do it yourself.
Grab your controller manual and search it up, you might learn other things from it. If you dont have the manual search for a pdf.
BTW, I have no idea what the code might be.

G32 will probably work.
Takes 2 blocks and you also need to pay close attention to spindle control code m3 m4 m5 word placement or else ypur tap will break off if you run it in single block mode.
1) feed tap to depth in the first block using correct feed/speed ratio and g32 and make sure there's an m5 is at the end of this block2) then in the next block, feed back out again using correct feed/speed ratio and g32 but with an m4 placed at the start of this block.

do it yourself.
it. If you dont have the manual search for a pdf.
This may be of assistance.....

Posted 21 March 2011 - 10:15 AM lathes are tricky
rigid tapping this may help.

Posted 21 March 2011 - 06:01 PM Yes G32/G33 is the ticket, you will not be able to rigid on a 10T, you'll need to use a floating tap holder. Some machines will alow you to M04 without M05ing.
so it's like
G97 M03 S200 G00 X0. Z.25 G32 Z-.5 F.03125 M05 M04 G32 Z.25 F.03125 G00 X10. Z 5. ...

Posted 24 March 2011 - 06:40 PM You'll want to change that G01 to a G32 because the feed override is active on a G01 not a G32
The tapping codes for the OmniTurn are somewhat generic for many Fanuc controls.....within the learning curve anyways.
