Bar Feed Macro Program

[hotiron]

Hello all...

I recently installed a LNS quick servo bar feed on my Mori ZL-150S. I am knew to bar feed jobs and macro programming as well. I know there are hundreds of posts about bar feed macros on here, but I can't seem to find one that fits my scenario. Plus understanding the Macros is a challenge for a newby. what I am trying to do after the sub spindle finisheds the 12th part is load a new bar and start another program loop. Basically the LNS loads the bar into the top-cut position, and after that the lathe makes 12 parts from the loaded bar. The lathe does it's own bar pull and part off with the sub spindle. I would like the program to loop 12 times and then call up a bar load with an M70. After the LNS loads the new bar start a new loop. The top-cut routine only runs once at the beginning of the main program.

Any sample programs would be greatly appreciated.

Hello Blake,
Post a copy of your complete program, along with any Subprograms that may be called.

Is M70 supposed to call a Macro program, or is that an existing function of the machine/control?

Regards,

Bill

Bill,

M70 calls the bar feed to load another bar. Attached are the programs for head 1 and 2.

Why doo you want it to run 12 pcs and then reload w/o the feeder following along?
Are you running very small D bar?

What happens if you ever have a less than perfect outcome sometime durring a bar?
How doo you plan to restart mid bar?


I have never used this feature, but I believe the way to doo this is to set the barfeeder to count the feeds / without feeding. I think this is possible.
Meaning that the machine is not the one dooing the counting, and the number of parts in the bar is double checked at each load - when the feeder verifies the bar length and compares to the part length.

If the issue is tiny bars, there is also a feature where you can use the LNS to feed out - verifying advancement, and stock length each time (this is a good thing) and yet the pusher will back all the way back out - so's not to rattle in a tiny spindle liner. Then at chuck open signal - it will rapid back in to the known last location of the bar, and then feed from there. Chuck close and it rapids all the way back out. This takes prolly an extra second or so, but that's about it.

Or maybe you are not running tiny bars, and simply don't know how these units generally are ran?


Point being that - since you are new to the application, I'm guessing that you are not looking at this the right way.
Did you buy this loader used?
Or did you buy it new and have LNS install it and show you how to use it?


The quickest way to doo 12 and load [your way] would be to loop your program through a sub-routine 12 times and at the end or beginning you call your barfeed "load" signal.
But again - this doesn't work well at all if starting mid bar.
If you let the feeder doo the counting - it will Shirley be able to start mid bar.
Again - I've never used it this way - but in this application, I would expect that when you would engage the feeder - the pusher would go find the bar and then rapid back out and then know how many part cycles are in that length.
If you doo this with the machine control (does NOT verify bar length) you would need to know how much bar is in it, and edit your counter, or subroutine loop count, or ....
Doesn't sound like a good application unless there isn't another - more better - way to doo it already - and I think there is.

OX. Actually the way you suggested would be better, I just wasn't sure how to implement that method since I am running 7/8" hex stock and need to implement an M19 spindle orientate to line up the collet hex with the bar upon every bar load. I have a 98 LNS quick servo and would prefer to have it do the counting and have the ability to load various lengths.

I purchased the LNS used and set it up myself...new to bar feed jobs, so I'm just looking for suggestions from the experienced

 

[Ox]

OK, you have the first year for the Servo model. (as doo I)

I'm not 100% sure how much of those options is available on the '98 unit, but an SII unit that I bought used - they were pulling the pusher back all the way each time. I changed it when I got it.

I think the '98 unit can at least count cycles without actually following along tho.
But I've never set it up that way, and you would need to read through the manual - or maybe just the pendant screens - and figger it out.
Or worst case - call LNS.

However - for 7/8 stock, and your only concern is indexing - then I would not use it in any of those fashions anyhow.
Doo you have the 1/2" carbon fiber pusher? That is all that I use, and would be fine for your 7/8 stock, and allow it to follow like normal.

As for your indexing concern, you want to doo that in your macro.
I have my spindle index every load - whether I'm using shaped bar or not - it's like Ragu - "It's in there".

This is for a Hardinge with an 18T.
Bill can help you edit it to your machine app.

OX....This LNS has the options to fully retract the pusher and let the lathe do the feeding as I am with the subspindle. It follows the lathe progress by counting how many chuck openings M11 (that equals parts made). As you can see in my my main program I take care of the bar pull with the sub spindle and part off. The bar pull by the sub spindle is +.03 and sets it up for the next face operation on the main spindle. The top cut N100, which is only used at the beginning at a fresh bar load to qualify an accurate first part bar end. M99 keeps the program looping while skipping the N100 top cut for the remainder of the bar. I guess the part I am having trouble wrapping my head around is when the LNS signals the lathe it has reached bar end what's the next process? I'm sure it has to jump into a sub that opens the main spindle collet (M11), waits for the LNS to signal bar load complete to top-cut position, close main spindle collet (M10), and then hop back over to the main program to start over. putting the sub together and understanding the process from bar end to bar load and resume cutting is where I am having trouble.

 

[Ox]

As long as you are in loop mode, it's not likely going to ever see the load.

I pull with the sub frequently as well.
I have not taken time to open your program yet.

I pull at 100 RPM and let the feeder follow.
I run slow so the pusher doesn't get all whoppered - like it would if it was running 1500 while pushing.

I'll look at your program later and show you how I would doo it.
Heading to a grad party now.



EDIT:

Real quick tho :

O1234
G97 G98 G20
G10 P0 X0 Z-3. (You would likely edit this to G54)
G0 T0 X15. Y24. (Y is my sub linear)
Z10. (2 lines = safe index point - and with a sub, you want the Z to be a second line)
M61 (bar change allow)
M56 (open sub collet)

N1 T101 bla

bla


In my header, the M61 is the M code that the macro needs to see to ask the barfeeder if it needs to change a bar or not. If the parts counter on the feeder is at 0 it will load a new bar. You can see the M61 in my 9023 macro. LNS tech did the wizardy to make that happen, but others here - especailly Bill can help you determine how and what code that you should use on your machine.

Also note that I still have the last part in my sub yet at this point.
This way - if I ran out of material, I know that the last part to check is right here.
Not lost in the pile of parts - likely somewhere near the top.
(Mine runs overnight frequently)


Again - if you pull at S100 the pusher won't get destroyed, and it's a much simpler life to let the feeder follow.
The pusher has a retract value and you should sety that for .200 or whatnot, and then as soon as you close the main collet, the pusher will retract .2 and you can then speed it back up.


This may be enough to get you up to speed - with help from the macro Gods here.

Your top cut should be burried in macro's like I have above and should be pulled up by the G70, if and when your LNS says that it is at 0 parts left.

Bill,

M70 calls the bar feed to load another bar. Attached are the programs for head 1 and 2.

Hello Blake,
Take a look in parameters 6071 to 6089 for the registration of the number 70. Its not common for a dedicated bar load, or bar feed feature to be provided that is totally PMC driven (a feature of the control). It is not something that is provided by Fanuc, but would be up to the MTB to implement. My guess is that M70 calls a Macro, or Subprogram.

In Ox's example Variables #1000 to #1133 inclusive are Interface System Variables, some Input, some Output. #1008 in Ox's example is an Output signal from the PMC and would be provided as an Input from the Bar Feeder is my guess without further information. Your system would be quite similar. Accordingly, I would be surprised if your Bar Feeder was not supplied with a Bar Load/Bar Feed program template to modify to suite your needs. There must be some I/O interface between the Bar Feeder and the Control. You need to find the Inputs used so as to use the correct Interface Variables in your program.

First step, determine if M70 is calling a Macro, or Subprogram. Second, check if there has been any programs supplied with the Bar Feeder. The I/O variables to use will be included in these programs.

First step, determine if M70 is calling a Macro, or Subprogram. Second, check if there has been any programs supplied with the Bar Feeder. The I/O variables to use will be included in these programs.

Bill,

The M70 is a Mori M-code on this machine. It specifically signals the bar feed to load another bar. I have tried it through MDI and it works fine...loads a new bar into topcut position. I checked all of the I/O links on the LNS PLC and communication functions are good to go between the LNS and Mori. I just need to get the code in place with my main program to automate this into a loop and load at end of bar. Attached is a section from the manual on M70, M482, and M482.

Will it load a new bar via M70 if the counter is not at 0?
It should just sit there and doo nothing.

When in AUTO mode, will it feed out when it sees the collet open in MDI?
And retract a second after it sees the collet close?

I've got the same feeder as you, as well as an S2.

Ox....what Counter are you referring to? Parts counter on the Mori? Yes it response to Chuck open and Chuck closed as you described

No - the "Parts Remaining in the Bar" on the LNS pendant.

If you have 2' of bar in the machine, and you have 2" in the OA part length field ....

....

Maybe we need to start at the begining?

From the pendant - hit MENU.
ENTER
key in your bar D
ENTER
Key in your OAL + .2"
ENTER

Now manually bring your pusher all the way FWD.
You want this to be maybe an inch (?) behind the collet face.
If that needs edited, move it to that point and note the value. (this will have changed from the old value with a new home - depending on how far from the lathe it was mounted)
Note the location on the pendant
MENU
page down
ENTER
Now you should have EOB position - or something like that.
Key in the new value
ENTER
page down
page down aggin
The screen now should be TOP CUT POSITION
the value in it currently is where your loader has been loading the new bar to.
If you want this edited, you enter the INCR value that you want it changed, and then hit + or -.

Now, if you have a bar in the chuck @ 1 or 2' long or whatnot, and you put the unit in AUTO cycle it will go up to measure the bar.
If you have a 2' bar in there, and a 2" part length, it should say that you have maybe 10 pcs left in the bar.
It should say this on the pendant screen at this point.

With the barfeeder in AUTO cycle and ready to rock and roll, with the door closed and everything, if you cycle M70 in MDI now, it shouldn't doo anything - b/c there is ample material left to run with.

Yes?

MDI = M11

Did it push?

M10

ox....I will check in the morning and let you know. What I can tell You is I have been through every nook and cranny on the LNS and set up all the information needed. Set the end of bar position with the teach mode, And also the top cut position. Also set up all the information on the part length as well. When I go into automatic mode the bar is loaded into the trough, and does everything all the way up to putting it in the top cut position... as soon as I close the chuck manually the pusher re-tracks all the way home is that’s how I have it set... pendant display says it’s in auto mode gives the part count of 14..I think the disconnect I am having is understanding the macro variables. I think I’m starting to understand that system variables 1000-1133 That was mentioned earlier are populated by the bar feeder as it works through each bar correct? As the macro program is executed it looks at these variables to make a choice as what to do next correct? If I’m on the right track with my thinking here I think all I need to do is implement the macro program you and Bill have posted.
