Questions: Puma MX2600ST

[Joe.B]

Hello good people of the forums!

This machine should arrive within the next couple of weeks. It is our first CNC of this caliber & we are very excited I'd like to get some questions answered before that. Help with any of these questions will be GREATLY appreciated! Thank you!


1. What are the codes for COOLANT ON/OFF & AIR ON/OFF for the main spindle & the bottom turret?
2. It appears that the sub spindle does not have to be all the way in its “home” position for machining operations. Please provide a programming example on how to set & lock the sub, say, 36” from the main spindle.
3. Please provide a programming example on how to use the bottom turret as a tailstock.
4. Can the part transfer happen with the door open?
5. What does “G50 C0” do? Is G50 also used to set a max spindle speed for G96?
6. Must the following be listed in this PRECISE order “G96 M3 S100 P11?” For example, is the following a legal statement that will execute the same: P11 G96 S100 M3
7. If the order is crucial, where must the gear command go? (high gear/speed, low gear/speed… which I assume is M161, M162, M261, & M262… yes?)
8. Is this a legal statement: M5 P11 P12 P21 P22
9. How do you “lock” the milling spindle for lathe-work? Please provide an example of how to do lathe work on the main spindle, then “flip around 180” to do lathe work on the sub spindle.
10. Please provide details for G368.
11. Why use G315 to stop a spindle instead of M5?
12. Is G98/G98 Feed Per Minute & Feed Per Revolution?
13. Please provide a programming example of one turret (ready and) waiting to cut until the other turret completes cutting. I assume M900 is used somehow.
14. I've read that "sync control" is M203, M204, M213, & M214. I've also read that it is M203, M204, M205, M214, & M215. Please confirm which is correct, & what each M code does.
15. G28 U0 W0 is typically used to home out the X & Z axis. Is that true for this machine? What does G28 V0 do? Please provide the home out code for all: X, Y, Z, B, & C
16. Please provide details of M289 & M389.
17. Please provide a programming example of a drilling canned cycle on the face of a part in the sub spindle using the bottom turret.
18. Please provide a programming example of a "part transfer" from the main spindle into the sub spindle (that includes a "sync").

Guess ill try to answer few of the basic ones here, 2600 is bit newer than our couple 2500LST types, but i'd guess the basic commands are the same, dont quote me here. I'll poke around the codes more from work tomorrow maybe, since i cant remember all from outmemory.

Aaand i might call milling unit as upper unit, dont confuse.

1. What are the codes for COOLANT ON/OFF & AIR ON/OFF for the main spindle & the bottom turret?

I dont remember the air commands for Main/sub spindles, but if you mean basic coolant codes for Upper unit(and bottom turret is same) is M8 On and M9 Off.... these are for upper unit only..-> M26 is coolant through tool and M27 is coolant through tool Off.

2. It appears that the sub spindle does not have to be all the way in its “home” position for machining operations. Please provide a programming example on how to set & lock the sub, say, 36” from the main spindle.

No experience here, only used A(sub spindle) at its home position(with exception of part transferring from subspindle to main). and we dont have to use any M code to unlock it, nor in our Gildemeister type machines, I'd just guess you have to move it certain position at the start of program, and make sure your workshifts are in right position also.

Aka G0 A500

3. Please provide a programming example on how to use the bottom turret as a tailstock.

(For subspindle)
Hum, simple example, read offset T05005 for example, close on part
G0 Z-20
X0
G302 B400/B-400(Direction) (B is the value for torque, theres a diagram on folders you should get with the machine)
(Syncro)
G303 (Torque off)
G0 Z-50
G28 U0
G28 W0

4. Can the part transfer happen with the door open?

No, not normally, but since im no parameter/switch expert i wont say a word more on this subject.(Theres M codes to overide certain things you need during part change via robot, aka open chuck etc., [sarcasm] unless you want to try force robot through doors [/sarcasm]

5. What does “G50 C0” do? Is G50 also used to set a max spindle speed for G96

Yes, G50 S2000 works for setting rpm limit. But normally your program should have these two lines after each tool change, if doing milling work. ->

G28 H0 (run spindle to home)
G50 C0 (set Caxis to zero, or however i should call this)

And whenever theres a line in the program for G0 C0, and turns the spindle to this position.

Between these two lines you can easily move all your milling certain degrees, by inserting extra line... example.

G28 H0
G0 H5
G50 C0

... these will shift the spindle C0 position by 5 degrees.. obvious.

6. Must the following be listed in this PRECISE order “G96 M3 S100 P11?” For example, is the following a legal statement that will execute the same: P11 G96 S100 M3

7. If the order is crucial, where must the gear command go? (high gear/speed, low gear/speed… which I assume is M161, M162, M261, & M262… yes?)

I dont know if 2600 machine has same stupid problem as 2500. Where lower turret is the master for subspindle and upper unit is mainspindles master.

This was hardest part for me when we got our machines, and still i dont know if 2600 type has same problem, but in any case.

If you want to do turning jobs on main spindle, you must have M5, and for subspindle its M105, no matter if you work with lower turret or upper unit.

I havent used both units on same spindle at same time, theres own synchro M commands for those.

For milling it was bit different, same principle, M35 for main spindle, and M135 for subspindle, _BUT_

As mentioned earlier, Upper unit is main spindles master, and lower turret is sub spindles, and you have to ask let say "permission" via M-code to poke into anothers territory (M211/M212). (Sounds stupid, dont know how i should explain this one)

And with these comes the certain order to place certain M codes in right places, specifically when choosing either you want to Mill or Turn, there should be good examples with the folders you get, if not, and if your 2600 doesnt have the same flaw(well, its not flaw, but i dont like, specially when comparing to siemens control ), then forget all this ramble.

8. Is this a legal statement: M5 P11 P12 P21 P22

9. How do you “lock” the milling spindle for lathe-work? Please provide an example of how to do lathe work on the main spindle, then “flip around 180” to do lathe work on the sub spindle.

Millling spindle is locked by default, and it can be unlocked via M101(And in variable while using G400 i think).
Ill paste some program later, i dont have anything home.



10. Please provide details for G368.
11. Why use G315 to stop a spindle instead of M5?

12. Is G98/G98 Feed Per Minute & Feed Per Revolution?

G98 Feed per minute
G99 Feed per revolution


13. Please provide a programming example of one turret (ready and) waiting to cut until the other turret completes cutting. I assume M900 is used somehow.
14. I've read that "sync control" is M203, M204, M213, & M214. I've also read that it is M203, M204, M205, M214, & M215. Please confirm which is correct, & what each M code does.

15. G28 U0 W0 is typically used to home out the X & Z axis. Is that true for this machine? What does G28 V0 do? Please provide the home out code for all: X, Y, Z, B, & C

Our fanuc controllers have increment letter below the axis, yours seems to be qwerty style so.

X=U so G28 U0
Y=V so G28 V0
Z=W so G28 W0
C=H so G28 H0

Normally i think G28 U0 V0 W0 for upper unit should be around middle and G30 U0 V0 W0 is for toolchange coordinates.

And for lower turret we have G28 U0 W0 middleish and G30 below the main spindle so it eludes robot and subpsindle during part change.

Both can be changed via parameters, you dont want the positions too close to soft/hard limits specially on lower turret since it tends to collect chip quite abit and it might work fine for months till it just starts to drop hydraulics suddenly during party change and you wonder whats the problem .

16. Please provide details of M289 & M389.
17. Please provide a programming example of a drilling canned cycle on the face of a part in the sub spindle using the bottom turret.
18. Please provide a programming example of a "part transfer" from the main spindle into the sub spindle (that includes a "sync").

.. and still, these are from 2500 type machine, might, or might not work with 2600, perhaps someone can give more experienced answer on this one.

Rather than asking on the forum just ask the Doosan Dealer that sold you the machine. They have all this information available in a succinct manual and it is fully explained in that manual. Very few folks will have access to the latest 31iA programming book and it is available through your local dealer.

mystiks - I sincerely appreciate your time in repsponding. Sorry I have not been on here in a while. I've been up to my ears with preparation for the arrival of this bad-boy. Seriously... thank you! I owe ya one.

Jaguar - "... just ask the Doosan Dealer..."

I know, right? Sounds simple? They should respond, right? Wrong. Dead wrong.

I do not wish to "trash" the dealer here on the world wide web. There is a lot to say, but I'll skip it. Summary: we've experienced many undesirable events.

The Doosan dealer is the one that can give you the best most accurate information. The documents are there, not here on this forum, although I have them but you need to ask YOUR dealer to put you in touch with the Applications department and they can send you a document that will answer all of your questions. The 2600ST uses a 30 series control so just about all of the M codes have been updated from the older 2500's with 18i's so nothing will translate properly. The correct information is critical to getting you going, not to mention getting a post to work for the machine. If you can't get answers at this stage of the game you are screwed when it comes to getting trained.

If you've had as much trouble with the local dealer as you claim, you should send the machine back.

Mjep, i dont have experience with 31i control/2600st machine, saw the machine at DIMF 2011. have to confess that i haven't bothered to go through much of the fanucs own manuals, our dealer always supplied us with few of their own folders which had specified information about exact machine and the control which helped us to get through the start.

Hopefully i dont have to tackle with more than 2 of these 2500st type machines that we have in our shop, so much frustration along the years.

I think they fixed the problem with lower turrets lines that they are covered properly, we run machines unmanned most of the time, chips stack on those and eventually one or two breaks and sometimes its a hell to find the correct one for leak.

But, nothing says that your dealer provides you with anything else than basic manuals, we had few weeks of training ourself, and new guys are trained by us, who got the original training, you should make sure that dealer provides you with all possible material.

Use the lower turrets livetooling with silk gloves, and properly unmount and mount the tools.

Wonder if 2600st's upper unit has any sensors/switches/anything for the toolpot, i mean if theres a tool or not. We use capto in our machines, and the tools that arent used for while collect oil/dirt/whatever in the chain, and if the dirty tool is switched for use and isnt properly locked we dont get any indication about it on 2500st machine.

I had one tool starting to rotate 7000rpm which wasnt fully locked

Coolant through tool is one itch also, if the holes arent big enough, we need to give delay after the off code, or multiple off codes, or change chuck. (Our problems started with smaller than 6-7mm drills)
