I have an Okuma MacTurn with an OSP 200 control the program has some p commands in which I cant understand what they are for or do. Here is a part of the program any help is much appreciated.
Thanks
Dave

P codes are used when a machine has 2 turrets (and usually 2 chucks as well) to either synchronize both turrets or to make the turret wait for something to complete before continuing. when the turret waits the axis control switches from that turret to the other turret. the part of the program that runs is the one with the lowest P number so a higher P number will cause the turret to wait until it sees the same number or a higher number on the other turret. it will continue until it reads a higher number then it will wait. without the P codes both programs (for A turret and B turret) will run at the same time which may not be desired.

here's a very simple example....
(any code on a single horizontal line shown here will run together)

(upper turret program)        (lower turret program)
P10 (wait)                    M8
                              G4 F5.0
                              M9
                              P20 (wait)
M8
G4 F5.0
M9
P30 (wait) 
                              M8 
                              G4 F5.0
                              M9
                              P30 (now the same P code is active on both sides)
(so now both turrets will run together)
M8                            M8
G4 F5.0                       G4 F5.0
M9                            M9
P100                          P100
M02                           M02

Where are the m100's?

[Dave Allen]

Thanks for the reply ForDav, apparently both turrets run from the same program instead of to seperate programs as on a mori with a fanuc control, so how do you determine which part of the program runs which turret.
Thanks

[fordav11]

the A/B turret and chuck left/right codes are G13/G14 and G140/G141
just google them for more info or look in your manual

[jamessiffel]

For Dave and chattaman, google Macturn multi tasking lathe assistant pdf, you'll find a very helpful manual that someone has translated into an English speaking friendly version of the manuals, for both macturn's and Multus's

Thanks jamessiffel, but I was asking about a different P value

[ChattaMan]

Sorry but can't find the Macturn multi tasking lathe assistant pdf.
Do you have a direct link

[fordav11]

it was a little difficult to find because the search words are wrong.
assuming this is it, try this one....
