Iam running a femco lathe that has a fanuc o-t series control.I've tried every canned drilling cycle that I know of and everyone in the shop as well.But nothing works! Does anyone have any Idea whats going on or what to do to fix this.All help is deeply appreciated THANKS
:drowning:

Whats wrong with it?

Whats wrong with it?

The drilling cycle does not work .I changed the parameter 0909#3to1 and it gave me 000 p/s alarm . I have tried every drilling cycle and everyone in the shop as well, but nothing works Any ideas?

[gridley51]

Why did you change the parameter and what codes did you try for the drilling cycle?

Mark.

I got the parameter off of another problem I was reading about the same but diffrent kind of machine.And the number was wrong it was 909.3 to a 1 . I have tried G73, G81,G84,G83,G74, it rejects every thing.

[gridley51]

Just had a quick look at an OT-A manual and it supports G32,G92 threading cycles and G34 which is variable lead threadcutting.

Michael82,
The last time I used a canned drilling program on a Fanuc OT control it was tied to a macro program (G65) from which variables such as depth, feed, dwell, etc. was entered. I remember not being able to "single-block" the program because it was tied to a macro program. The control was on a Hardinge Conquest, however, and they may have their own proprietary program embedded in the OT control.

Oops! Sorry got mixed up and thought threading.Our OT book says G83 but apparently it does not work for us either and drilling cycles are being written long hand.
Our W&S with OT uses G74 and it doesn`t work either apparently.So thanks very much,you have found me another job to add to a very long list. :-)

I have a 10TF, and I think you may only have a G74 drilling cycle, which doesn't have a retract to any plane, just a chip-breaking peck. You may have to have a two-line entry, as some controls demand. I don't know the format of those two lines. Someone else?

[lshingleton]

Try this ----Have a good day---Hope your machine has macro capability

[Michael82]

Can you explain this program? Is this macro and if so why do I have to run this program and not G73 or G83,G81.That is my problem I need to be able to run a canned cycle

Do you have an example????

Whats that have to do with canned drilling cycles?

[Michael82]

If there is anyone out there that could give any examples that work on a fanuc o-t series control preferable on a femco lathe

[lshingleton]

This program creates you own canned cycle in the machine using a macro
Something may be wrong with you software--ie never purchased-----or parameters missing and it could be awhile before you get running -this one will work if you have macro variable turned on in that control-give me an e-mail address if you need it explained or tel -number?

[beege]

I don't have an example of a two line, because I don't have a control that requires it. However,

G74G99X0Z-1.K004000F.004 works on my machine, where X and Z are the usual suspects, and K is the peck increment, and the retract amount is a constant determined by a parameter (6217 on my machine).

This is useless to me, and I end up writing the drilling operation longhand.

[gridley51]

"Whats that have to do with canned drilling cycles?"

I have already explained I got muddled up,so,no need for the sarcasm.

[positiverake]

These are options, G74 should come standard, although pretty limited, if you have macro B ,(also a option) I have a good drilling program.

[Billmac]

Give this a try:

N200 G74 R.010 (R is the retract amount for the peck)
N210 G74 Z (final depth) Q(peck amount without decimal) F (feed)
