G4.1 Fanuc

[Kipa Crawn]

Ive been reading the message board for awhile but never posted anything so this is my first time. I'm wondering if anyone has any suggestions for using G41/G42 cutter comp in the control when using a Fanuc Series O-M contol. I've only been on this machine for about 6 weeks (joined new company) and can't seem to figure out the cutter comp. I was using a Haas and it was clear where to put the cutter diameter value but I can't even find where to put a D value in the Fanuc. Is it in the parameters somewhere? I want to program circles with Mastercam and set the cutter comp to "control" so I can circle mill and adjust the diameter of the cutter to size the bore accordingly. We are using a Dahlih MCV1020B vertical mill with Fanuc O-M controller from 1994. Any help is greatly appreciated

If I am not mistaken it will read the d as an h. the diameter values are taken as h in the geometry store so i usualy make the diameter offset for tool 1 h21 tool 2 h22 tool 3 h23 etc.I am also using a dahlih 1020 so it sounds like exactly what i am doing.You can use whatever h value you want i just find it easier to get the opperators in the habit of always having a diameter offset equal to 20 more than the tool #. I beleive if you leave a d value in the program it will look to the h value anyway.

Fanuc controls don't have 'H' and 'D' offsets the same way that Haas or Okuma controls do. The offset register merely stores values that can be accessed for either purpose. The typical way to handle this is to use, say H1 for tool #1 and D51 for tool #1. If you use comp in control put the cutter radius value (typically) for T01 in offset 51.

As mentioned, you enter the values associated with H5 and D15 in the offset screen of the controller. The O-M controller is a scaled down Fanuc...but you'll get used to it. I'm guessing you also have the scaled down keyboard that doesn't have all the keys...that's fun.

I always use WEAR in Mastercam that puts a G41, or G42 and depending on the machine, our Monarchs will only accept cutter comp, when moving a linear move, it won't accept a G41, G42 on an arc, so I have to use the lead in lead out and make sure I have something in there.

Thanks to the "members of the board" for the info. I tried it out and as long as I use the radius value of the cutter being used everything works great. I tried reading the manual but didn't get too far. Next time I have a problem I'm posting on the board and leaving the book in the drawer.

Our Fanuc manual works well as a dust collector. It collects at least .25" of dust every 6 months. I just have the ALARM pages tabbed. I love to see dust on the book...that means everything is running well.

You should have a Parameter you can change to use a radius value or a diameter value. On the Fanuc 18 it is Parameter 5004 bit 2 ODI "The cutter compensation value is a radius value (0)/diameter value (1). Probably some useless trivia, but feels good to use some of that expensive training that the company sent me to.

Also on the 18 you can enter the offset number say 51 and it will bring up a soft key for # search and when you push it you go right to the offset #. Don't know if it is the same on the O control, but worth a try.

on our fanucs we use wear comp in mastercam, and set "job setup" to add 30 to the tool #. At the machine, just set the offset to "0" till you need to cut more material. Then set the offset for the amount you need to take out. Our param. set for radial, and setting the offset minus tells the control the cutter is undersize, meaning it will move over to take more out of the hole. Clear as mud, right?

A FANUC alarm code, also called a FANUC fault or error code, is how a CNC control indicates there is a problem. This error message could indicate issues with either the machine itself, be that electric or mechanical. The FANUC error code might also indicate an issue with the g-code program.

Use the list below to interpret what exactly the fault code is trying to communicate. If you require a replacement part, know that MRO Electric stocks thousands of FANUC CNC replacements.

Hi Running a series 180i-M , the machine halts with no error or alarm. ctrl+F2 or any other function key is impossible. The softkeys in fanuc software work with mouse. The problem resolve after some time but randomly. The rest of the computer functions work fine ( alt+tab, alt+F4, using other applications..)

any idea

I own a machine from Newwai

And after the operation, I discovered the following

When I am inside a program and finished it and I want to go to another program

I do not find that the entry button for another activated program must be filled with the machine in order to do that

And the button dedicated to the barbarism of the bar is an act of an act

I have a Miyano mill with an O-M fanuc controller. I get an overtravel in the +Z error. It appears that the error is when the tool change carousel does not stop in the correct position. There are 2 magnetic limit switches that both have to be illuminated to show the controller that the tool change carousel is in the correct place. Sometimes only one switch is illuminated due to the cam rotating past one of the switches. Why would the tool changer sometimes overtravel in its revolution? The machine will run fine for an hour or so and then the error happens. We put a metal object in front the sensor that is not turned on and then step rotate the tool change carousel. This brings it back into proper alignment and the machine will run.

Any ideas what I need to do?

Thanks in advance for any assistance you can provide.

I have a fanuc control SERIES O-TC TYP AO2B -OO98-B501

machine, Lathe and the machine belongs to the Jolly company

I have a problem that the batteries have expired, and when I opened the machine, it was found that the parameter was not present

When trying to download the parameter, the control panel to run the motors does not activate

I want a way to solve this problem
