OKUMA ROCKS!!!!!!!!  

After you get used to them you will no doubt, love them. 

We have a deep internal grooving part that we are having trouble finding tooling for.

Perhaps some of you lathe guys can help me out.

Here are some pics to give you an idea what we need,

 

I have had two tooling companies no-quote this....

Ouch. 

      that's all I got.    

When all else fails.......................................

Its the wife's fault.  

Trying to turn and bore together.   I want to have top turret run bore bars and lower turret do the O.D.

 Could always contact ICAM and they can whip you up a post and simulation for that machine.

LMAO!!!!!!!!!!!!   :unworthy:  

Ron, this is from your post.

Ray I made a post for that machine years ago. I have all of that dialed in for that machine. Might need to be updated from X4 to the version you are running, but all of the wait code stuff is worked out using the mi and mr values in the misc. The G13 and G14 is also sorted out in the post. I should have some old pinch turning programs I did years ago you can look at. Some of the long shafts we did and other little things. Machine still have that .002 dip near the chuck?

I think you only made one program for that machine Ron.  I tried to find it but I had no luck.  

As far as that little dip,   I just started using a second offset to cancel that out.   works perdy good.

I like the machine, just never had the time to figure out programming the second turret.

Bottom turret uses the same x values as a top turret, so X+ is away from the centerline. As for wait codes, I have to put them in by using manual entry. The post I have wants to put wait command at every damn toolchange but they're only necessary when when you need to time the turrets. Do you want a sample text program, or a sample Mastercam program?

Thanks,   I so wasn't sure about the -X values.    Just the text would be helpful.   My Mastercam program I believe is correct.   (looks right in backplot)  LOL.

Thanks again.

We have had an LU 15 in here for years and we only use the top turret.  The boss man wants me to

start using the lower turret on it.  I have a post that works, but it doesn't put the "P" codes in the right places and on the lower turret, all of the X values are X minus.   I don't know if they are supposed to be negative or not.   So my question is:  Does anybody have a sample program for me to look at? 

Thanks guys.

Yea, I had to go rescue my wife. She locked herself out of the house. Great show though.

That sucks guys.    See ya next time.

Many thanks to you guys for the help on Friday.   

I ended up using what CJep sent.   and looks like it will work pretty darn well.  The only thing I don't like about it, is the fact that I cant take the credit for it.        Thanks again.   

Are you wanting to roll/pivot the tool up as it comes to the front?

I don't think you will ever get exactly whats drawn without violating the part unless you use a lollipop cutter. Even then that tool might get kinda flimsy.

We are going to use a 1/2 dia adapter to give some support. 

But I could rotate the part and repeat it.   It might work.   

Is this more like the motion your looking for?

That's a lot closer, but its not getting the radius in the front.

Aw screw it, i'll post it.   

I'm not a mill turn guy at all what so ever.  I'm not a mill guy for that fact.

I have what should be an easy 1 tool program that I can not figure out.  would anybody like

to take a look and pull me out of the fire.  

If you are interested PM me with an email address and I will send it to you .

Thanks in advance, Ray.

I'm looking forward to it.

Your it guy is wrong. Lol

Your bringing the beers foggy.

Is anything planned for Oregon?  

Hey Thainz,   

Take a look. 

REGISTER NOW for MCAM X8 ROLL OUT EVENTS!

Mine started as black, I changed it to DODGER BLUE!

The only thing I can think of is he isn't defining his stock.  His thread is starting inside the bore at Z-.8739, if its not defined properly it would exit thru the material.

I just posted that thread real quick with my proven post and this is what it looks like.
