Another MPosp7 question

[jeff]

Is there a way to NOT have a tool change and force next tool if I am only using 1 tool?

Say that I am using T11.

Right after my G56H11 line it puts in a T11 on the next line.

And at the end before my M02 it puts in an M06.

I am thinking it's probably a boolean expression of some sort that says: IF and THEN.

But I don't have a clue how to write it.

I am not familar with that post. No stagetool switch?

[mayday]

post a sample Jeff, whats an MPosp7 for anyhow? :curios:

[jeff]

it's for an Okuma OSP700M control.

Just wondering if it would have anything to do with this:

ptlchg0 # Null tool change 1002

n, sgplane # Restore G17 tool plane

pcan

 

Or this:

ptlchg # Tool change 1002

gcode = 0

if zh <> 0, n, sgcode, zh

if zh <> 0, n, xh, yh

Here's how mine works (fanuc 18I)

 

In ptlchg_com;

 

look for;

code:

---

pbld, n, next_tool, e 

---

and replace it with;

 

code:

---

      if t <> next_tool, pbld, n, next_tool, e

---

Not sure about the M06.

The problem area is *next_tool

If I remove the * it doesn't stage the next tool when using multiple tools.

But it solves my problem when using only 1 tool.

 

Can I write something like IF next_tool<> current tool then *next_tool????

[jeff]

OMG I can't believe I figured it out!

I changed it to:

if next_tool <> t, *next_tool

 

Jeff teh post guru.

Watch out fellas here I come!

 

Tim, I didn't see your reply,until now.

But it looks pretty close to what I wrote.

Thanks for the help guys.

I'll try to be quicker next time.

This is how I got around that problem.

You can call the next tool as "empty" in an okuma

code in my post is as follows:

ptoolout # Output tool information for current tool in spindle

if t_flg > t_flg2,

[*n, "CALL OT", "VC1=", *bltool, "VC2=", *speed, "VC3=", *next_bltool, e

else,[*n, "CALL OT", "VC1=", *bltool, "VC2=", *speed, "VC3=EMPTY", e ]

[jeff]

In my previous reply I solved the tool call if I am only using 1 tool.

As for the tool change at the end I created this:

if t<> next_tool, pendprog

if t = next_tool, "X-20.", "Y20.","Z20.","M09", e

 

Where I created pendprog that states:

pendprog #whether or not to output an M06 at end of file

"X-20.", "Z20.", e

"M01", e

"M06", e

"Y20.", e

"S50",e

 

The S50 is the line directly above the M02.

I noticed that on our Okuma, when the machine is sitting for a period of time while the spindle is locked in orient,the toolholder get pretty stinking warm!

We have had to replace parts in our spindle 3 times already and I think this may be affecting that somehow.

Any of you Okuma users out there I suggest you do the same thing.

You set a spindle speed to release the orientation at the end of a prog???

[jeff]

Yes
