Haas Trunion Brakes - 5 Axis

[Josh T™]

Hey Guys,

 

I'm using X2 with a modified generic Fanuc post flavored to taste for a Haas VF series mill. I 've turned on the post switch below:

code:

---

 use_clamp   : 1     #Use the automatic clamp Mcode  

---

It will output the brake release/engage M codes on a normal index:

It's probably not recognizing the switch string on the 5X path but I don't know how to add it.

 

Thanks for the help in advance,

Josh

JP (AKA Mr. Haas) you out there?

[bogusmill]

I have the same problem and I suspect its in the post here.

 

# --------------------------------------------------------------------------

# Primary axis lock/unlock

spunlock M13 # Unlock Rotary Table

splock M12 # Lock Rotary Table

# --------------------------------------------------------------------------

# Secondary axis lock/unlock

s_slock #Target for string

[crazy^millman]

Josh are you talking about a brake or a Lock?? The Integrex uses a brake for all 5 axis work and then used a Locking type system for all 4 axis work. The Generic 5 axis post does not support this in only supports locking the axis not braking the axis. You will have to write you own logic in for that. I recommend you look at the MPLMASTER yes for the lathe. They have all the logic written in the post to support not only brake but clamp as well.

 

code:

---

use_clamp    : 1     #0 = No, 1 = Clamp

use_brake : 1 #0 = No, 1 = Brake

 

pclampbrake #by operation # clamp_code 0=clamp, 1=brake, 2=off

# clamp_flg 0=clamp, 1=brake, 2=off

# mi7 - Clamp Code Override

# 0 = Default post decision

# 1 = Force Full Clamp

# 2 = Force Brake / Mid-Clamp

# 3 = Off

 

 

#if cuttype = one, pxyzcout0 #Turning off

#if abs(cuttype) = two #Right/Left Face cut brake unless rotary type is off (0) or Y (3)

#| abs(cuttype) = three, pxyzcout2 #Cross cut brake/clamp

#if cuttype = four, pxyzcout4 #Y axis substitution brake

#if cuttype = five, pxyzcout5 #Multisurf Rotary brake

[

clamp_code = 2

if cuttype = 1 | abs(cuttype) = 3 | (abs(cuttype) = 2 & (rotary_type$ = 0 | rotary_type$ = 3) & not(millcc)), clamp_code = 0 #clamp

if abs(cuttype) = 2 | abs(cuttype) = 3 | cuttype = 4 | cuttype = 5 | millcc,

[

if clamp_code <> 0, clamp_code = 1 #brake

]

if opcode$ = 3 | opcode$ = 16, clamp_code = 2

if use_clamp = 0 & clamp_code = 0, clamp_code = 2

if use_brake = 0 & clamp_code = 1, clamp_code = 2

Just some tid bits from that post. Now you will have to modify if for milling and the spindle stuff all needs to be stripped out. May have to add so mill5 logic to it as well and might look to the ops stuff from MPMASTER and use its logic to make that turn on and turn off the brake for 5 axis verses trying to use the mill5 variable though it would be your best choice.

Thanks for the advise Ron. I'll give it my best effort. I didn't know if this was a common thing or not. I've seen Haas Trunions run super smoothly on true 5X paths and I'm just trying to get ours to run at that level... you know... that whole "Continuous Improvement" stuff I keep hearing about!

[Josh T™]

Ok Guys...

 

I've worked on this for 8 months and I still can't get it right.

 

I'm using the Haas Trunion MD in X3 with minor changes (props for it being super close!) and its the same problem as before... No M11/M13 and M10/M12 on 5X paths. Works great on 3+2 paths but not on true 5X. This is weird! I can't find it anywhere in the post and from what I see the logic is the same. Can someone help? We're porting heads soon and I don't want any issues.

 

Thanks in advance,

Josh

find these lines...they are in more than one place

 

code:

---

     if use_clamp & not(opcode$ = three | cuttype <> zero),

---

change to

 

code:

---

      if use_clamp & cuttype <> zero,

---

that would be the unclamp portion

 

For clamping...basically the same.

 

find

---

      if use_clamp & not(opcode$ = three | cuttype <> zero),

I also added it to the null toolchanges area

Josh you need to do a little editing, I will send you a sample

[Dan@home]

Maybe a dumb question, but why would you want to clamp and brake 5X movement?

[bogusmill]

I manually input M11 and M13 early in the code when using our Haas trunion post and it works great. It sounds like your engageing the brake for 5th axis work which obviously doesn't smooth up your cuts. The sticker on the box under the control reads:

M10 engage 4th axis brake (A axis)

M11 release 4th axis brake

M12 engage 5th axis brake (B axis)

M13 release 5th axis brake

[Don S at Barefoot CNC South]

Josh

Did you get it figured out yet?

[Josh T™]

Thank you JMC!

 

By playing with the opcode statements I got it to work how I want it to. I knew it had to be something in those statements.

 

In regards to Dan's question, the reason for using the lock/unlock commands is for free movement on the 5X paths. If you don't use the M11/M13 unlocks with true 5X work the machine will dwell for the brake release which (in some cases) will gouge the parts. I'm using inverse feed rates on the rotarys and unlocks to try and smooth out some of the porting work we've been trying.

 

Thanks for everyone's help!
