OT Fanuc 6M start lines and DNC

[joe m]

We have a 1981 Hitachi Seiki VA40 with a Fanuc 6M that we purchased used. The machine had been neglected and sat for some time. After tending to some neglected maintenance we have the machine running quite well but have the following problems, or annoyances. While these are not all Mastercam questions the users of this group have proven to be very helpful in the past. We have been running Fadal’s for the last few years and have forgotten the ins and outs of these older Fanuc’s.

 

Program start:

When a program is started the machine must be at the reference position or it will crash.

 

Programs start and end as follows.

DNC:

For the life of me I can not get straight answer on how to tell if this machine is cable of DNC! I know how DNC works and what it is, been using it for as long as I’ve been a machinist. How can I tell if this machine is callable and if so how do I set it up? I have the machine sending and receiving to a pc but need to DNC.

 

Tool change:

This machine has a side mount tool changer that is random access. How can I change the V9 mpfan post to pre-stage the tools for a tool change? I.E. have the T# before the M6.

 

Thanks in advance.

Try setting the machine in tape mode, start sending the file and press cycle start.

[Craig-B]

Oh, Joe M

For the tool change, Check your the post setting for pre-stage tools.

stagetool : 1 #0 = Do not pre-stage tools, 1 = Stage tools

You should get somthing like the following.

Tried setting the knob to tape mode as you described, nothing.

When you press the OPR/ALARM button the OPR softkey, is there a setting in there for DNC?

[Craig-B]

Joe M,

Did you have the PC set to send while in tape mode. The PC waits on the signal from the machine to start sending the program.

1. Set machine to tape mode

2. Setup the PC to send file.

3. Press cycle start.

The machine should send a signal to the PC to start sending the file. That's all that I do.

[joe m]

Don't have an OPR/ALARM button or OPR softkey. Don't have any softkeys. Softkeys, row of buttons under the screen right? I think softkeys came on 10M and newer.

I have a settings key, the settings screen has a setting for RS232C. I have it set to 1.

[Matthew]

Ok. I used a Fanuc 0-M that had a setting under that menu that needed to be changed for DNC to work. Thought I'd take a stab that maybe your 6M did too. Sorry.

[joe m]

FNMI what are you using for dnc software?

[Craig-B]

The Cimco Edit that's in V9

[joe m]

FNMI,

can you send me your Cimco settings?

Joe,check your email

Most Fanuc 6 Controls can not DNC via the RS232 port. You must use the tape reader port and emulate the tape reader with a BTR. Once the machine is in TAPE Mode, the BTR will "trick" the machine thinking a paper tape is still on the control and run DNC. For more options, visit our website: www.cncnetworking.com
