Capture output of next operation

[Dave Loveridge]

I am trying to get the value of a MI from the next operation to use as a switch. How do I go about this.

Any help is greatly appreciated

Problem is everything is done in series, so it's hard to grab something that hasn't been processed yet.

 

You'd prolly have to buffer the entire part, then pull what you need from that. (PITA)

Dave, Matt is right on target as far as I know. What exactly are you trying to do in the program? Maybe we can puzzle out some more options

[Dave Loveridge]

I want to use mi4 to input all the codes I need to use the Barfeeder and the sub spindle to pick off.

[chris m]

So I'm assuming that you want to set the mi value in your cutoff operation and then it would automatically post your code BEFORE the cutoff op starts? Is that right? Can you post some actual code the way you want it so we can see what you need? There may be other ways to do this.

Well if you are wanting to do this in a spefic operation with a mi4 then you can hard code oyur post for this. Look at the exmaple I put for for a Fadal yeasterday something about material removal speed or something like that. I think that will point you in the right direction only problem if that you will have to fiqure out where in althe post to put it becuase I dont have lathe here.

Why not just turn on the MI at the start of the op you want to run it at? Instead of the end of the previous op? Just move the code in the post to the appropriet place.

 

That's how I do my M00's with MI. When I want the proggie to stop at the beginning of a milling op, I switch it on on that op.

btw, you might be able to get sneaky and look in the tool buffer for a parting tool, then run a function based on that.. provided you have the build tool table switch turned on.

Rekd is the one that taught me how to do this trick an now I use it all the time. I havea 5ax post right now that uses all mi and all but 2 mr vaules in my post.

Ron, have a look at the extra drill parameters, might be something to think about for any drilling ops that use MIs, in case you run out...

Thanks Matt, I am about to run out I have 18 used and can think of ten more things I would like to add but no mi to control it. I am blowing everyone's mind with the Thermwood. I just got an awsome job for it. 16" x 15" x 28" solid block of ABS remvoing about 75% of the Material. I figured it will start at about 350lbs and end up right at 45lbs when done. There are 2 different of these parts. I am trying to get a release but of course they are for a trade show and that I dont want someone to steal our idea comes up everytime.

Millman,

 

Just an idea...

I am coming from a computing background, so I might be geeky and let me know if this confused you.

 

You have 10 misc integers to use, if you make it becoming a bit, then a misc integer variable become multi variables.

 

For example, a value of 256 for misc integer 1 means the eight bit of that variable is true or it means the eighth variable of the misc integer 1 is equal to 1.

 

However, this will only works if mp.dll can do bit comparison just like C language.

 

Did I make sense? I am not sure myself...

 

I just make this post and I am about to sleep. So, ignore me if this is nonsense and useless...

[Rekd™]

CAM, you can test for any value in MI.

 

code:

---

If MI3 = 4, 

[

DoThis

]

 

If MI3 = 5,

[

If MR3 = .125,

[

DoThat

]

DoTheOtherThing

]

Rekd,

 

There are 10 misc integers.

 

Let's just take one misc int. We usually use misc integer for turning on/off a feature. So, a value of 1 means turn on a feature.

 

An integer can go up to 32000 which is a 2^16.

 

If we look at misc integer as a bit(0 or 1) instead of just an integer, we will have 16 variables. With that theory, we have 160 misc integer variable instead of just ten misc int variables.

 

If I do this, the misc integer 1 is set to 8 and I have the following code in post:

code:

---

coolant = 8

if and(mi1,coolant) = coolant

#turn on mist coolant

---

so, when I set my misc integer 1 value to 8, it will turn on the mist coolant.

 

Doing this will give you a total of 160 misc integers instead of just the 10 default misc integers.

 

I had not done this but I think it will work.

Some may not realize that you have access to the Misc Ints & Misc Reals of the Operation about to be processed at the end of the current operation being processed.

 

Example:

Program with 2 tools.

You've set MI10 = 1111 on Tool #1

You've set MI10 = 2222 on Tool #2

 

When MP processes the NCI, just before going into the PTLCHG (toolchange) postblock for Tool #2, it has read the Misc Ints & Reals that are set for Tool #2

 

The Misc Ints can be accessed in for this situation in the PMISCINT postblock and PMISCREAL for the Misc Reals.

 

You can test this by adding this line into the PMISCINT postblock of the std MPFAN.PST ->

 

"*-> mi10 = ", ~mi10, e #

 

You'll see something like this ->

code:

---

 N144G0Z.1                               	pzrapid prapidout 78

*-> mi10 = mi10 2222. pmiscint 84

N146M5 ptlchg1002 pretract 118

N148G91G28Z0.M9 ptlchg1002 pretract 118

N150G28X0.Y0.A0. ptlchg1002 pretract 118

N152M01 ptlchg 120

( 1" DRILL TOOL - 2 DIA. OFF. - 2 LEN. - 2 DIA. - 1.) ptlchg ptoolcomment 120

(THIS IS THE OPERATION COMMENT FOR TOOL 2) ptlchg pcomment2 120

N154T2M6 ptlchg 120

N156G0G90G54X-3.2978Y4.3749A0.S250M3 ptlchg 120

N158G43H2Z.1M8 ptlchg 120

N162X.1495Y6.007 pdrill_2 126

Is pmiscint call before null tool change too?

 

ptlchg0 #Call from NCI null tool change (tool number repeats)

 

Please advise. Thanks

[Paul Decelles]

Yes, pmiscint is called prior to ptlchg0 (null tool change). Shut off fast mode and set bug2 to a negative number and you will see all of the post blocks visited.

[Rekd™]

Cam, what I'm saying is, you can get as many MIs as you need, we're talking tens or hundreds of thousands of them.

 

code:

---

      if mi8 <> 0, 

[

n, "( MISC INT 8 VALUE SHOWS ", mi8, " )", e

]

---

With this in mind, you can enter any integer into the MI and based on it's value, do something different for EACH value. Like a Select Case statement.

 

Of course, you'd play hell remembering them all, but hey, that's ok..

 

Roger, that's good info, I didn't realize that. Thanks!

That's why I posted it

I was sure that many "didn't realize that".

You can save off all the MI# and MR# values in a the program off into a buffer file. You would not need to buffer "the entire part". The MI and MR values are available in the PWRTT pre-read routine. But I'd always suggest to try to find a different way to do what I'm trying to accomplish to avoid doing that - unless that was the only solution.

[Trevor Bailey]

I have a post almost finished that is for a Fanuc 18i-TB control. It will have all fuctions supported, caxis, yaxis, pick off, sync for cut off, bar feed, auto stop, etc...

 

It will be available thru the local dealer network. I will post back here when it is completed.

[chris m]

Trevor can you put that on Jay's ftp...?

 

What?!?!?

 

That should've already been on the CD..

I see what you have done, now what do I use to access the pmiscint.

[Dave Loveridge]

Sorry I meant Roger

[crazy^millman]

Cam Displie good thinking for one.

 

Roger thanks for that tip.

 

I am using alot of these for axis controls like maxuim B angle rotation, Safe unwinds postions in Z, I have anohter that sets the Z height for 5 axis maching on the Thermwood. I have others that are doing things that limit my abilty to use intergers to activate different functions on this post as what is stated here. I would have to then create a complex libary of spefic postions and then do an intger equation to cover all the vaules I would need. My post also supprts the G52 Lxx workoffset which is support by Mastercam and the workoffset on the T-plane page. I am working on some other things that will give me things I am looking for in this post. I have the M48 Feed rate override and the Timer sub also supported by this post and they are turned on by Mi in my post if I want them there or not.

 

I had to coem up with contional stamtements for this as for something I need to work all the time when doing 5 axis work where as in 3 axis work some things are just not needed and add extra unwanted moves. I also added the 5 axis cicrle mill Macro support to my post using the drill cycle as a control.

 

The 3 axis machine posts are pretty good at this point I have them dialed in pretty good to support just about everything we need for both machines.
