hello i recently hit into a okuma with 2 spindles, 2 turrets, and i managed so far to use the upper turret to cut on spindle 1, then on spindle 2, while lower turret was stationary

program is:
G13
G140
do something
G141
do something else
M02

i wish to continue with lower turret, not syncrnous wiht upper, but simply after the upper finishes, so i tried these :

G13
G140
do something
G141
do something else
G14 --- here it starts to error
M02


thus i can not activate lower turret and continue, at least not inside that program

---

so i made another, simpler :

G13
G140


G00 Z+10 G91
    Z-10
         G90


()


G14
G141


G00 Z+10 G91
    Z-10
         G90
M02

but here, upper and lower move simultaneously, not 1st upper, then lower

i guess that being dual spindle dual turret, then it has some modes which go simulatenous by default, and i believe that it looks through the program, and where it sees
13 140 is one side, and then 14 141 is another, and it starts to act simultaneous.

So what are the modes, that by default, trigger simulatenous ? are they driven by 13 14 or 140 141, or 13 140 and 14 141, thus what are the codes combinations that trigger an independent machine mode ?

How to add P into above program, and make it behave no more simulatenous, but lower to execute after upper ?

Please, i don't know exactly what to ask, but i need help / kindly

Definitely need to insert P codes into your program.
P codes will dictate the sequence of operations when operating mutliple turrets.
Not having ever worked on Multiple Spindle machines, I cannot comment with regard to them, but P coding with turrets works well.
P codes must always be larger than the previous code, i.e. you cannot program P0010, P0020 then P0015, the P001 will cause an alarm.

Turrent Select
P Code
actions
Turret Select
P Code
actions
rinse and repeat.

If you want both turrets to execute at the same time then use the same P code for both turrets.

hy broby yup, i am still messing with it

please, for a pinch turning code, generated by igf, as attached, why is there, on left side ( 13 140 ) :
... P0010 at N0003 and N0113
... P0020 at N0106 and N0114

thus why are there similar P codes, for same side ? kindly

P codes within shape definitions are used to synch both turrets during the cycle.
The P codes within the shape defined do not have to be sequential to the P codes with in the main program.
if you are pinch turning a roughing cycle this has the effect of making sure each cut is synchronised.
Finishing cycles, like you are using, (G87) will just synch each step of the profile.
Seems excessive at the start of the program to define and synch the start up of the spindle. Usually is enough to just startup from one turret then carry on after that.
It has been 30 years since I did any serious pinch turning and then it was with a Two turret Single chuck system. (LC20M OSP5000L-G)
