Cancel hpcc before index B axis and turn it on right after

Need some help here with HMC post  (

When in HPCC in Fanuc16i (we just added this option), the cnc skips right thru B rotations. No alarms of any kind.

I need to modify the post to turn off hpcc before B axis rotation "phsm_off" and turn it back on right after the rotation "phsm2_on".

 

Any help/pointers appreciated!

 

TIA

That seems to have done the trick:

 

if fmtrnd(prv_cabs) <> fmtrnd(cabs),
            [
            if safe_index,
              [
              if lock_codes = one & not(index) & rot_on_x, pbld, n$, *sunlock, sunlockcomm, e$
              phsm_off                                                                                                                                           <<<added this line
              pbld, n$, [if not(index), sgabsinc, pwcs], pfcout, e$
              if lock_codes = one & not(index) & rot_on_x & cuttype = 0, pbld, n$, *slock, slockcomm, e$
              phsm2_on                                                                                                                                           <<<added this line
              pbld, n$, pfxout, pfyout, e$
              ]
            else,
.
.
Is there any place else I need to add it?
 
TIA

Hey Ron, yeah... I did the same in all of those places. So far so good.

What's weird is that the machine would just skip over B rotations while in hpcc mode...scary

 

Yes that would be a major issue for me. I would be on the phone with the machine builder or dealer and getting an answer if that is by design. Glad you got it figured out, but not something I think you should have to do.

Tim,

 

Its pretty simple...

 

G0 G17 G90 G54 A0. X.3125 Y0. S2000 M03
G5.1 Q1 (HIGH SPEED ON)
G43 H1 Z2.
Z1.1
G1 Z1. F50.
X0. F16.
X-2.
G0 Z2.
G0 G90 G49 G53 Z0.
G5.1 Q0 (CANCEL HIGH SPEED)
G0 A270. X.3125 Y0.
G5.1 Q1 (HIGH SPEED ON)
G43 H1 Z2.
Z1.1
G1 Z1. F50.
X0. F16.
X-2.
G0 Z2.
M05
M9
G0 G90 G49 G53 Z0.
G5.1 Q0 (CANCEL HIGH SPEED)
G53 Y0. A0.
M30

 

If I don't cancel the high speed, the A axis won't move. The program will continue running tho.

When we added the 4th axis to this machine, A guy from Doosan came out and wrote a custom ladder on the spot. I figured it was an issue in the ladder. The machine is a Doosan VM925. A very solid machine BTW....like anything out there, it has its quirks.

Here is mine:

X0.
X-.75
X-.9
G0 Z11.

Z11.
M11 (UNLOCK)
G05 P0
G54.1 P2 B270.
M10 (LOCK)
G05 P10000
X2.375 Y9.1541
Z11.
Z2.65
G1 Z2.55 F420.
X-2.375 Z2.45
X2.375 Z2.35.

Again, If I don't cancel HPCC, the B axis won't move, but the program will go on.
I got the post figured out to take care of this, so so far so good...

Yep, this is a syntax issue and it's documented by FANUC.

 

You should really cancel HPCC, AICC, AIAPC before issuing a G49.

While it is not technically wrong, G49 has to be read before you can activate High Speed Modes again.

 

All High Speed modes are issued on a per tool basis.

However, if you issue a G49 without cancelling HSM, you will get results you do not like.

 

Based on what you are both reporting, It appears that both machines also have indexers as opposed to full rotary axes.

This may not be the case, but if HSM is properly formatted you will not have any issues with rotation.

 

It looks like Mark's may have something going on that's slightly different as I don't see a G49.

Mark, where are you activating HPCC within your program?

The machine is not an indexer. It can be run as a full 4th, as long as the high speed is not active. As far as canceling the command, its been a while since I played with it, tho when we first got the machine I messed and messed with it till I found a place where it would work. This machine was very picky about the placement of the G5.1 Q0 command. I played with it till it worked and left it at that....

Hi Tim,

But you're right.

Out 10 HMC's here, this is the only one with not FULL 4th axis (index only). That could be it.

You may also be having the issue based on where you have started it.

It should be started before engaging a TLO with G43.

 

This may not be the case since it's the older actual HPCC format.

G05.1 needs to be started before a TLO.

 

You might want to double check if your clamping/unclamping M-codes are actually resident subs and not embedded functions.

I've seen customized M06 programs cause issue for users.

It's probably not the cause but it's worth looking at.

 

On your machine it's probably because you have a strict 3-Axis HSM.

 

I'm not sure how FANUC is optioning this stuff now.

They may actually tie it to the number of continuous axes licensed for the option.

Or it may just be a ladder that was written without consideration for rotary indexing.
