Hi,

We have an old twin turret LC30 Okuma That I am currently having issues with.I run programs all day using the A turret,but go to use the B turret and it doesn't wish to co-operate-and the only info the manual gives me is how to use the b turret simultaneously,not as an independant stand alone turret.Was wondering if anyone out there can shed some light or supply me with a sample b turret program to get the ball rolling.Any assistance would be much appreciated.

Have you tried programming G14 at the start of the program?
G13 = A Turret
G14 = B Turret.

Is there any Turret selection switches on the operator panel? There should be as you need to be able to select which turret you want to use when in Manual mode.
By pressing the B Turret switch (button) and having G14 in your program, you should be able to run the program for B Turret.
Cheers
Brian.

if you're wanting to run only the B turret, you do need to choose that with the selector button. you also need to activate the interlock button for the B turret. so you'll be choosing the B turret in two places.

[malzow57]

if you were looking to run both turrets sync'd, this might help.
of course both turret interlocks should be off.

The question is about balanced cutting, do I understand correctly?

Error, I guess. Since OSP5000 doesn't support blank definition for animation as well as tool shape

[fordav11]

it's also too complicated for a newbie to understand.
try this simpler example.....

Seems like there is much discussion on "balance" cutting programming.
DKCC was originally asking "How do I run a program only on B Turret" I find that most seem to be going off topic.

The answer is that you NEED to program G14 at the start of the program so that the machine can load the program and activate it for the B turret!
From memory, if you did not do that the machine would default to G13 which is for A turret.
The 'example' program shown above, is for this example ridiculously complex, it is no wonder everyone is off on tangents from the original question.
A 'simple' program to face a part to 50mm long at front face, rough and finish turn a diameter of 115mm from a bar diam of 132mm, with a 2.5x45 chamfer could go something along these lines:

Even if BOTH turrets are switched ON this program will only run on the B turret.
The program uses three tools, Tool 1 used to face the part to length,
Tool 2 to Rough the OD, and Tool 3 for Finishing.

Mr. broby says:
DKCC was originally asking "How do I run a program only on B Turret"
and I noticed:
how to use the b turret simultaneously,not as an independant stand alone turret
there is a big difference between working two turrets simultaneously and balanced cutting, that's my point to make clear at first

Hey Al, The part about using the B Turret simultaneously is referenced as that the only mention in the manual is how to do balanced cutting, NOT how to use the B turret independently of A turret.
You cannot take part of the sentence like you have, as the context is totally wrong.
I absolutely agree that working the turrets individually as against simultaneously, is two entirely different situations and needs to be addressed as different questions.
The question asked is HOW DO I USE B TURRET ONLY?
