HAAS SL-10 Help

[MES]

i need to work with part puller but when i move out in z give me alarm chuck open i know is open please how can i set this operation

[Ron Branch @ Verisurf]

Make sure you are using the correct codes. May have to M19 the chuck if it has an C axis to do bar pulls. Give a call to HAAS and they should be able to point you in the right direction very quickly.

 

BTW(By the Way) welcome to the Forum.

 

HTH(Hope that Helps)

I called to HAAS, and they told me that off parameter 278 (line 9) CHUCK OPEN CSTART, but when you do that the machine do not recognize if chuck if open or close when turning and you crash the machine if you forgot close chuck.

[FLHX95ci]

Haas lathes don't have a prox switch on the chuck, so they never know if the chuck is closed or not anyways. It just watches the sequencing of the footpetal switch basically.

 

Turn Off #278 and see if you get "Chuck Open" message on the machine while you cycle the chuck. If it does, then the machine won't start when it "thinks" the chuck is open anyways.

You will have to pull out (move in Z with an E not F for feed.

[Sbarner]

I just went through this. I recommend writing a little text program to be accessed with the manual entry "toolpath". Here is a sample of mine:

code:

---

 M01

 

(BAR PULLER)

G0 G54

T0808 (****NEED TO EDIT EACH USE****)

G98

G0 X-.75

Z0.5

G01 Z-1.375 F300. (****NEED TO EDIT Z EACH USE****)

G04 P1.

M11 (UNCLAMP)

G04 P1.

G01 Z-.15 F50. (****NEED TO EDIT Z EACH USE****)

G04 P1.

M10 (CLAMP)

G04 P1.

G01 Z1.5 F300. (****NEED TO EDIT Z EACH USE****)

G0 X10. Z10.

---

Please note the M00 command for program stops. Also are some G04 dwell commands to be certain that the collet or chuck is all the way open before the bar puller starts moving. Hope this helps. Cheers!!

I have used a custom drill cycle to achieve the same thing.

[Sbarner]

Hmmm. I had never thought of that. That would be an interesting option to explore. The older "set in their way" machinists here are not happy about the way we're doing it now.

 

I've never messed around with custom drill cycles. Would this be easy for someone to do who is moderate post editor? Using MPLMaster?

Here's a sample

 

peck1$ is the pull distance.

 

code:

---

 lmisc1$          #Canned misc #1 cycle, lathe  # Stock Pull Cycle added <---------------- S4A

result = nwadrs (strw, peck1$)

result = newfs (2, peck1$)

"(STOCK PULL)", e$

pbld, n$, "G94", sg01, depth$, feed, e$

if drillcyc$ = 6, coolant$ = 1

pscool, e$

pbld, n$, "G04", "P3000", e$

pbld, n$, "M24", e$

pbld, n$, peck1$, e$

pbld, n$, "M25", e$

if drillcyc$ = 6, coolant$ = 0

pscool, e$

pbld, n$, "G04", "P3000", e$

pbld, n$, sg00, "G95", initht_z, e$

#pbld, n$, e$

[Trevor Bailey]

i have used a sub program stored in the control and then used misc values to toggle where i need the output. if you leave it in the control, it is better to modify if you have different sized pullers, etc....

[Bryan Johnson]

On Haas, you can NOT single block through a bar pull. If in single block, you get the chuck alarm.

 

Take it out of single block, and it will run without error.

[Bryan Johnson]

below is what I use for bar pull on haas.

using Stock Advance, edit free.

Because it outputs "W", it is very easy for operator to adjust part count for any length bar.

Thank so much for you help.

I get it and run good.

[MES]

thank so much to Bryan johnson that point is perfect to me now i get it in continuous mode. i do not disconnected parameter 278 and run good.

 

Thank bryan

[Sbarner]

Interesting. I could've sworn that I just did a single block through my bar pull program. I did have to switch parameter 278:9 to 0.

 

Perhaps this is something that Haas fixed in their latest software update. Our machine is brand new.

[Sbarner]

That's the first time I've seen the following lines:

code:

---

 result = nwadrs (strw, peck1$)

result = newfs (2, peck1$)

---

What do these mean?

[Sbarner]

Ok. I think I figured out that the newfs is to define the new format statement to the variable; in this case, changing the peck1$ to a #2 format statement from whatever it's default is.

 

The nwadrs...hmmm...is that changing the address or letter that is output with the string? Instead of peck1$ being output as a Q, in this case it would be output as a W? Is this correct?

[Bryan Johnson]

if you switch parameter 278:9 to 0, you would be able to single blok through, BUT, you will also be able to start a program with the chuck not closed (not good).
