Good day!

I am going to be using a Micro 100 threading bar (ITL-050200X) which has a .022" neck, to do some threading in 4140 HTSR. Has anyone used a bar this small on an LB? I'm wondering if there's a cutting mode that works well for a bar this small?

Thanks

You are the man...it works again. Thanks Doug!

Does anyone know why our Okuma LB3000 EX II MYW, started giving alarm 1770, Door interlock 3? Right before that happened, I had locked the SS C-axis (M110) and after I was done, I unlocked it (M109). Then my jogging with the doors open, no longer worked.  I tried shutting down, but obviously that didn't work. Any input would be appreciated.

Thanks for all the thoughts, it's appreciated!

One obvious advantage for Mastercam Lathe is you can program off line while your machine is running.

I believe you can do that with IGF too, but I suspect the machine is usually down while

you are building a new program with IGF

You're right, when using IGF, the machine is down. Apparently they have a PC version of IGF but I believe it was pricey.

To add to gcodes comments it also gives you a permanent source file which an be used for other machines and can be easily edited for similar parts.

I do aerospace job shop work and the company has had Mazaks for a number of years using Mazatrol. Despite adding a new one a couple of years ago they have finally decided to abandon ship especially as we are approaching post and go from the programming dept so we are exposing some of the short comings of the conversational machines.

But as JP says it really depends on your work, aerospace job shop is reasonably unique.

A permanent source file would definitely be nice since we're running both Okuma and Mazak Lathes.

Our DMG C-Axis lathe has an Siemens 840 D controller with Shop Turn software on it. We use this for about 90% of the programs but we still have Mastercam and a working post to do some of the more complicated parts.

 

 

Right now I use Mastercam Mill to generate some code  for more difficult parts and then I just insert it into my IGF program. It would be better to have the lathe module and a post for it. The easy parts could still be done with IGF.

One big thing to consider is the quality of tool paths and options available in CAM software versus IGF. Tool paths to take advantage of multi-function groove tools, Prime turning, etc. You also have a lot more control over finishing tool paths and blending in a CAM software. 

Good points to consider, especially the blending.

Really going to come down to the work you do. Lathe by itself only offers C axis milling. If you want traditional milling then think you would have to get at least Mill, but what level of Mill you need I don't know anymore since they don't say on the website. Best to get a quote from your reseller which should be In-House and go from there.

We already have 5 seats of level 3 mill, so that part wouldn't be a problem, I was just curious to see if anyone knew if it had a significant advantage over using conversational.

Hi,

I'm just wondering if anyone can tell me if it's worth getting Mastercam lathe for an Okuma LB3000 EXII MYW over using IGF?

Thanks.

I can't keep up with all the responses guys, one at a time please, haha!

I'm wondering if anyone out there has a program for pushing to a stop on an Okuma LB3000 EXII using a LNS QLS 80 S2?

Thanks a lot for the pdf! I just saw it now and it's extremely informative. I sure wish our local AE had information like that!

Much appreciated!

After thinking about this a little more, it sounds like the AE is not familiar with the use of the Mid-auto manual function. Where this comes into play is touching off for a zero offset. When you call a tool in MDI, the tool offset is active, but if you put the machine into manual/handle, it cancels the offset. Then if you try to touch of a part and CAL the Z, the tool offset is not accounted for.

Instead, after calling the the tool you want to use to touch off with in MDI, turn on Mid-Auto Manual, leaving the control in MDI. You can handle the tool into position and CAL Z with the tool offset being accounted for.  

Great advice Doug, thanks! I didn't know that Mid-Auto Manual would work for that. That will be helpful.

I appreciate your help guys. Have a great day!

Yes what I learned when running Okuma's 25 years ago. Tell them to bring in a better Application Engineer that understand modern manufacturing methods and practices.

I would like that but their applications guy is the only one in the area and he hasn't even used a sub spindle Okuma before.

That is one things that always puzzled me about the way some people thought the way to use these machines. Does it have a Tool Eye? If so there shouldn't be a need for a Master Tool. Should be able to set a position relative from the Face of the Chuck to the Face of a Turret. Once you have established that then you should be able to work from those 2 places to do what ever you need with what ever tool and jaws/fixture and call it a day. Multus Machine don't require this and ask them to help you set the machine up like a Multus.

 

Exactly. It's a new machine and I want to set it up so that it's fairly easy to run. The "master tool" seems weird. Yes, it has a tool eye. On the subspindle side, I can't use the tool eye because of the length of the tools.

What do you mean by "Master tool"

The guy the dealer sent out said that you have to create a master tool. Basically, he wants us to take our finish turning tool and calibrate it so that the z will be zero when touched off. All tools touched off after that will reference off of that tool.

Good morning,

I'm not a fan of having to create a "Master Tool" for the LB 3000 EXII MWY. Maybe it's because I've never seen anyone explain it well. Even our trainer was stumbling through it. Does anyone have a detailed, step by step list on how to create one properly?

Thanks.

I appreciate your input!

I had that switch on before I posted my question but it wouldn't allow me to go past the stroke limits. I was thinking that maybe it only lets you come back from a crash etc. when it's traveled past the limits?

Does anyone know where the parameter is for overriding the y axis limit switch so that we can have access to the additional bolts that hold on the cover that is between the y axis box ways?

Okay. That's what I'm working on right now. Thanks Doug.

My groove is off by 1/2 the tool width. The Id is perfect and the Od of the groove is big.

Hi, when doing a face groove using IGF, it works well in graphics, including the x and z positions. Somehow, when it goes to the actual cutting on the subspindle, it makes the groove OD too big. The ID is perfect. Does anyone have any tricks to this besides entering the improper numbers?

Hi,

I'm wondering if anyone can let me know how they use Sandvik's Y axis parting blade on their Okuma lathe? It looks like IGF doesn't support it. My guess is that you have to program it in g-code. Any help would be appreciated.

Thanks.

Hey Titanium,

I remember reading a thread here a while back (5+ years ago) that mentioned having a good graphics card resulted in faster verify results.   

On my laptop I verified your part in roughly 1 Minute and 10 seconds using Mastercam 2017.  I'm just wondering what your computer specs are on the system that you are attempting to verify this part on?  Below are the important specs of my system.  My Laptop has an integrated graphics card but I turned it off in the Bios since I was having issues with it.  

 

Hey Chris,

In-House Solutions came to our shop and also thought it was our system. It ended up that our set-up was better than what they had. With the settings set to where we need them, their results were no different than ours. They admitted that there was a problem with Verify and that's where it ends. I'm not sure if CNC will ever fix it properly.

On our system, for this part, X6 verify takes 13 seconds (12 seconds to play and 1 second to compare).
In 2017 with the precision factor set to 1, verify takes 6 minutes 42 seconds (4 minutes 45 seconds to play and 1 minute 57 seconds to compare).
