Adding M339 code in milling post

[Columbo™]

I am trying to add M339 (thru spindle air) to tools that use thru spindle coolant ONLY with no positive results.

 

I get it to post on all tools (not what I want), is there a way to get it to post ONLY to tools that have the M50 (thru spindle coolant) active?

 

The machine is a Okuma MA50. If the air does not blast the coolant out we have spindle rust/rot problems. The spindle has been rebuilt three times and the machine is only five years old.

 

I hope someone can help, right now I imput this code manually, but it can get missed on very large programs, so I would like it automated.

 

 

Thanks in advance

What version of Mastercam are you using? If you're using X or newer, you can set tools to run multiple coolant options.

Can you use a boolean expression?

Something like this: If pcool(or whatever your coolant switch is) If pcool = M50 then M339

I am currently using X, hope to be upgraded to X2 soon. When I use the multiple coolant options it removes the m9 and replaces it with the m339. I guess I am doing something wrong there!

 

I am also wondering if this is a common problem with okumas?

Set options like this

Dont understand ?????

 

Set options like this ???????

 

Like what ???????

he is showing you how to use the x type coolant option.

I guess it would depend if you are using a post that supports x style coolant

It should be fairly simple to put the m339 in the post.

Are you running the correct mixture? Maybe a new type of coolant would be easier.

[Columbo™]

The problem is with small drill with ID coolant. The pressure is so intense the coolant backs up past the seals in the spindle head and does not disipate, therefore the rust/rot. Also when this happens the 60 Rockwell pins get crushed and the spindle needs to be rebuilt. Th mixture is good and we have tried different coolant to no avail.

Maybe I misunderstood......are you wanting simultaneous Coolant AND Air through the spindle or Air AFTER the drill is fininshed?

Columbo,

is this what ya are looking to have?

N200 G0 Z10.0 M5

N210 M9

N220 G30 P1 (HOME MACHINE TO TOOLCHANGE POSITION)

N230 M331 (AIR BLAST TO CLEAN TOOL)

N240 G04 F12.0 (DWELL FOR 12 SECS )

N250 M9

N260 G0 Z30. M05

N270 Y18

cadmonster66,

Yes, that is what I need to see.

 

Air when drill is finished and after M9 and ONLY when thru spindle coolant is used.

Columbo,

sorry been busy what post are you using and maybe i can take a look see . I have added that to couple post i am using for my new Okuma but really need to see what your post is doing to help you out

I did it with something like this...

 

first, I made a flag

 

code:

---

airflag     : 0     #Thru spindle coolant air blast flag

---

Then, right after your coolant is called up in your toolchange, I added this

code:

---

      if coolant$ = 3, airflag = 1

---

and finally, in the pretract section, I added this

code:

---

      if airflag = 1,

[

pbld, n$, "M331", e$

pbld, n$, "G4 F12.", e$

pbld, n$, "M59", e$

airflag = 0

]

---

and it works...

I got it to work when i turned off

 

cool_zmove : no$ #Coolant off with last move

 

 

and added this

 

 

pbld, n$, sccomp, *sm09, *sm05, psub_end_mny, e$

 

if scoolant = sm08_2,

[

pbld, n$, sm339, e$

pbld, n$ "G04", "P10", e$

]

 

When I use coolant$ = 3 I either get nothing or it gets posted to all tools (depending on where I insert it) regardless of m8 or m50.

Hey there John, Thanks for response, Not sure if what I did is the solution, but it seems to be working.

Finally upgraded yesterday to X2
