Milling question on Doosan 2000SY

[Clarence L Cook]

I have a Doosan 2000SY lathe with live tooling, sub spindle and y axis. What I want to be able to do, is mill two flats 90 degrees apart on 1/4" diameter rod while holding the material in the main and sub spindle. I would like to know what the best practice might be for this and what the code might look like. I think I need to command an M135 after an M35 to allow the sub spindle to free wheel while the main spindle indexes.

 

Any help is appreciated.

 

Kind regards.

Seems pretty straight forward. Best practice is what ever works. Email MTB Solutions and talk to Tim. He will be your best resource on these machines.

[Clarence L Cook]

Thank you Crazy^Millman.

 

I don't know who MTB Solutions is. I think the dealer for North Idaho is CNC Machine Services out of Oregon.

 

The machine is new to me and our first lathe with a sub spindle, so I am feeling my way around the machine and trying to learn as quickly as I can. I don't know if there is some special trick to what I am attempting to do.

 

Kind regards.

You really need to read the manual.

There are plenty of good examples there to get your feet wet.

 

Here's a manual that should help.

https://dl.dropboxus...AMMING rev2.pdf

 

Keep in mind that there may be some differences, depending upon the vintage of your machine.

If it is labeled Doosan only, and not Doosan/Daewoo, the previous manual and the codes below should be good.

Doosan standardized all the M-Codes across the Turning and Milling lines back in 2009-2010 when they went to the 30i series and the 0i-TD.

If your machine is prior to that change over, it will most likely have an 18i-TC control.

Here's a cross reference chart to the current M-Codes.

https://dl.dropboxus...TC_20090825.pdf

 

M03 P11 is CW Main Spindle

M04 P11 is CCW Main Spindle

M05 P11 Main Spindle Stop

 

M03 P13 ( or P21, depends on the machine) is CW Sub Spindle

M04 P13 ( or P21, depends on the machine) is CCW SubSpindle

M05 P13 ( or P21, depends on the machine) Sub Spindle Stop

 

M03 P12 is CW Live Tool

M04 P12 is CCW Live Tool

M05 P12 Live Tool Stop

 

M35 engages the C-Axis on the Main spindle and enables the live-tooling to be called (Milling Mode).

M135 engages the C-Axis on the sub-spindle and enables the live-tooling to be called (Milling Mode).

M136 will synchronize the C-Axis Main and -C-Axis Sub.

M137 will cancel the synchronization.

M34 disengages the C-Axis from the Main Spindle allowing it to freely spin (Return to Turning Mode).

M134 disengages the C-Axis from the Main Spindle allowing it to freely spin (Return to Turning Mode).

 

Keep in mind that the Y-axis on your lathe is very limited. It's a total of 4.1 inches of travel.

The closer you get to X0 centerline you will lose Y-axis travel as Y is a non-orthogonal virtualized axis.

Thank you Tim,

 

I have the 21i control. The machine is a 2006. I purchased it used back in March. I think when I said "new to me", I confused the fact that it is a used machine.

 

I haven't seen a P code after any of the M codes. My M code for live tooling forward rotation is M33 and M35 is live tooling stop.

 

For me, it is learning "how" to read the manuals is as important as to "what" I have read in the manuals. I have never had a machine like this. The sub spindle has added a whole new level to what I am doing here and I am still just beginning to scratch the surface as to what this machine is capable of compared to what I have had in the past. I read everything that I can and try to figure out ways that I can incorporate it into what I do. This forum has been a tremendous help in my education to better myself and to improve my efficiency in the work that I do (usually relatively simple 2 1/2" stuff).

 

Kind regards.

I meant it has the 18i Control.

The manual I gave you the link to is still a good reference.

All that will be different is the lack of the P-code for the spindles and having to cross-reference the new M-codes to the old.

The programming syntax will still be the same.

[Clarence L Cook]

Thank you Tim,

 

I took a quick look through it and it looks very much like the manuals that I have. I will give the newer manuals a more thorough examination in the next few days.

 

I just haven't seen an example of how to hold onto the shaft with the main and the sub and index the part. I have seen the examples with indexing in the main or the sub but not both. That is why I mentioned allowing the sub to free wheel and drive the indexing with the main. I just don't have any experience doing that yet so I am not sure that is the proper way to go. I hope to begin some experimentation in the next week or so.

 

Thank you for your help.

[crazy^millman]

The whole idea of main and sub spindle come into play. Synchronization of both normally comes through a Mcode process like Tim laid out for you. M35 so when you have the main as driving or Master Spindle then M136 should take control of both. Now if both need to be in the C axis mode M35 and M135 to use M136 on that machine I am not sure. I believe he mistyped the M134 as I would think it relates to Releasing the Sub Spindle since on most Fanuc controls the M1XX code control sub spindle stuff, but I think you get the point. Next question is who or where did you get your post for that machine. Without one you are asking for all types of problems. Thinking Mill/Turn requires a different type of mind set and process thinking. Controlling everything comes down to how far ahead you are looking. Also do not get trapped into the idea everything must start in the main spindle. Sometimes it is best to start in the sub and then transfer to the main.

 

You put up good files and pictures and such and we will be glad to help as best we can. Shooting off one liners without a lot of information does not give us enough to help. Best of luck and keep learning and growing.

[Clarence L Cook]

Thank you Crazy^Millman.

 

I got my post from my reseller in Sandy, UT. It is specifically for this machine, but I had to make some changes so that I was more comfortable with it. Some examples are: The tool table is in accending order, the tool table now allows for the same tool number but different offset values, moving x home before changing tools. Pretty minor stuff, but I am more comfortable.

 

I have gotten the machine and MasterCam to do most everything that I have asked of it, and I can make it work in the main or the sub, but both together is new.

 

I am finding out that Mill/Turn is a whole new mind set. I am just trying not to have my thinking be to narrow. A whole new world awaits.

 

Kind regards.

Well sir then you are well on your way and look forward to seeing the work you get done and how you are able to make the machine do things you need.

[Clarence L Cook]

Thank you.

 

I will post here when I come up with a solution.

 

Kind regards.

Like I said give Tim a call he knows that brand of machine better than just about anyone.

[Clarence L Cook]

Wow, thank you both.

 

Tim, I will look over that sample code. I have to have my M code cheat sheet pages out to understand it all. I have had troubles in the past with the various interactions of the M codes, but I have been starting to understand.

 

Thanks again. I will post what I end up doing and how I went about it.

 

Kind regards.

Clarence

[Guest MTB Technical Services]

Clarence,

 

I just did that sample from memory but you should be OK.

 

It will run on your SY.

 

You only have the upper turret correct?

[Clarence L Cook]

Hi Tim,

 

Yes, I only have the upper turret.

 

Kind regards.

[meangreen94z]

sorry to bring up an old post but we are having a problem getting out doosan 2000sy to start milling. we have it transferring to the sub parting off, moving b back, then rigid taping, after the tap finishes the live tooling goes in to do its hex milling. but we get a c axis commanded while in spindle mode. we have the m135 in there but it still alarms out. any ideas?

[Clarence L Cook]

First off, did you do an M291, reverse axis assignment?  It makes the A axis (normally sub spindle) and turns it into the C axis (normally main spindle).  When you are finished, you will want to do an M290 to put it back to normal.

 

Could you post a snippet of code so that I can compare it to some of the code that I have that I know works.

 

Which control?  Mine is the 18i.

 

Kind regards.

Clarence

[meangreen94z]

heres a snip of the bottom of the program. mind you this program ran 100 parts, we changed it just to tap a different tap now alarms again with C in it before instead of the A it would not run right without alarming. after swapping to A's instead of C it ran fine for the first batch

I have attached a snippet of code that ran just last week.

 

The biggest difference I see is I am not using M35 in combination with M135.  From what I read in my book, the order of M35 to M135 matters and if I understand my book correctly, then it appears you have the order correct.

 

I also don't use M119.  When parting I synchronize the sub to the main, so angularity is maintained.

 

Finally, I use M291 to change the axis assignments.  I mainly did this because Mastercam wanted to use C for everything and I just haven't gotten around to fixing it.

 

Hope this help.
