Hello

I have here a FANUC 16iM running a Daewoo 630 horizontal.
I need to make a back-face with a tool that requires the spindle to be oriented and fed through the pilot hole.... but it wont.
Of course i could dry-run it or use G00 and be super carefull on the potentios but that is fairly dangerous for some operators.

Can anyone direct me to the parameter that would allow G01 movement with the spindle in M05 mode ?

Any help is appreciated !

[txcncman]

Done.

[Al_The_Man]

It appears to be a Horizontal mill?
In some cases the OEM will write the ladder as such that if the spindle does not show a spindle up-to-speed signal in G01 then it does not move.
Also in some cases it is also written in the ladder if the up-to-speed signal fails a feed hold it implemented.
Just a guess?

You might try M84. This is either "G01 possible with spindle stopped" or "4th axis mirror image." depending on which manual you look at.

If it's mirror image, M80 cancels all mirror image.

[weibelmarco]

Thanks all for your help !

The program is in inch/min.
The program runs smooth on a Matsuura with Fanuc 30i.

Al is thinking right up my alley.
I have to find the parameter(s) that ignores the 'spindle rpm reached' check signal when automatic feed motion.
I am close but still...


Anybody done that lately and remembers the para# ? LOL
Al ?

If it's mirror image, M80 cancels all mirror image.

I really want the machine to act 'normal' by correcting the parameter.
It is a second-hand unit and the previous owner must of ordered it that way or disabled the function for operator safety.

M84 hmm... i dont even know at this moment what that does on the Daewoo! Isn't that the spindle syncronisation command ?
Will check that out too!

This causes to start machining before the spindle has reached it's programmed speed.

3708#0
the spindle speed arrival signal (SAR) is:
0 not cheked
1 cheked

3715#0
This parameter specifies an axis for which confirmation of the spindle
speed reached signal (SAR) is unnecessary when a move command is
executed for the axis. When a move command is issued only for an axis
for which 1 is set in this parameter, the spindle speed reached signal
(SAR) is not checked.
0 Confirmation of SAR is necessary.
1 Confirmation of SAR is unnecessary.

Very much so !
Thanks for reconfirming this viorel !
...but still no feed after the changes to those parameters.

The M84 works great !!!
Thank you dcouper !
M85 or 'Reset' cancels M84

Now if i would want to remove the necessety to enter M84 for a program that requires feed with spindle. Lets say, (without having researched that corner yet) the M84 triggers a relay to close a loop that allows G1 with M5 and i simply bridge the corresponding contacts, practically activating M84 when power to machine is turned on.
The relay i chose as example, it could also be a parameter.
... anybody has experiance in what could cause problems with 'normal' machining operations?

I have 4 machines on divers fanucs that run the same program without problem but not that Daewoo. Because she is the oldest and slackiest of the bunch the managment gave me freedom to do what i (and you!) see fit.
With the parameters savely backed up of course

[dcoupar]

There should be a blue(?) book in the electrical cabinet that has a list of the parameters and keep relays. I don't know for sure but there may be a keep relay that controls this.

[samu]

another way could be to write a custom macro called by M05 that enable M84
it is very simple :

09021
M05
M84
M99

Don't worry, M05 will act like a normal M05 within the macro even if it is called by M05.

[weibelmarco]

Uhhhh , I like the macro !
A very elegant solution. Thank you samu !

I still want to fiddle with what M84 actually triggers on that Daewoo...physically and/or digital.
I will keep everyone posted on my findings...

I cant express how helpfull all of your info has been so far on my quest to break down the relationship between spindle and automatic feed.

Keep 'em coming !

Cheers

I has same problem today, and i got figure it out by change the parameter 1402#0 (NPC) to 1.
Hope it helps.

Maybe you should add G95 at first of the program, for change type of feeding into feed per minute. Feed per revolution requires spindle to rotate.

Post is nearly 10 yrs old.... machine is probably replaced by now.
