Fanuc M-code List

[Phoebe Sibilio]

CompleteCNC g code list with m-codes for milling in the Fanuc, LinuxCNC, GRBL, and Haas CNC machines dialects. We give a quick definition for all g codes along with a link to tutorials and examples of how to use it in CNC programming. Click the g-code link (if any) to visit a tutorial from our popuplar Online Free G-Code Training that shows examples and teaches how to program CNC machines using the g-code commands. This page is your ideal g-code reference.

This page lists all the G code commands used in CNC programming and tells what they do. It also gives links to tutorials and examples. G codes are single-letter commands that tell the CNC machine what to do. They may command motion (i.e. tell the machine where to cut) or do things like turn the spindle on or off.

Not all CNC machines use G-Code. Some CNC machines may have both g-code and other ways of programming, for example, alternate languages such as Mazak's Mazatrol or Conversational Programming. Others may have an alternate language and no ability to execute g-code at all.

hey guys, i'm using the doosan mill/turn post to run our yama seiki live tool/y axis lathe with Fanuc 31i control. it works pretty well for the most part so far, but it posts some M110/M111 and M90 codes that the yama doesnt like. i looked through the post briefly but couldnt figure out what those are, what they do and how i can disable them.

If you open post in editor and scroll down where list of M codes is, you can compare description with M codes from your machine manual and change most of them to output correct code with given function.

M90 unlocks your spindle for it to function as a lathe. M89 (on Doosan) would be the command to lock it (like a 4th axis indexer on a mill). Do you have another code to substitute instead, or is your desire to have it removed altogether?

@Anonymous besides having it programmed in the control tool table how does the lathe know if it is an axial or radial live tool? At least with the lathe I operated (NLX2500) you just told it live forward or reverse and even then there was a setting in the control to reverse the direction apart from what was in the program/M code.

At the moment I mostly use axial tools because radial tools are mounted in the middle of turret and need a lot of clearance to even put a hole on side of a small part in 8" chuck, never mind doing anything else.

I added some comments that get posted above NC code to remind me to edit M codes for rotary tools and also edited start of the program and end of each sequence to park turret midway between main and sub spindle.

It's been working just fine for over a year now, I am only shortchanged when it comes to canned cycles for rotary drilling and tapping, not really needed all that often so I just looked up the book and saved templates to copy and paste when I need them.

Fanuc Oi-TD control is having some odd ways of doing things, for example, in polar mode, tool must first go to spindle center line then it goes to where it is programmed to mill feature, even machine distributor was surprised when I brought it up but thing is in the book and there is no way around it.

Winds of change are blowing in the shop so I think some decent equipment is coming in soon to replace dying Haas DS30SSSY and I wouldn't cry crocodile tears if Yama was replaced with small 2 axis lathe with tail stock.

Here is something you and others may find useful, I downloaded two PDF manuals that have tons of information in general and perhaps specific information you may be looking for, depending on whether you have Yama Seiki or Yama Sucky, difference being in options and type of control.

To avoid using different posts to produce code for individual operations, I am looking into modifying Nakamura Tome mill-turn post that has canned cycle support, that way I just copy and paste working parts of code from my old post and edit M codes.

M codes in these manuals are identical to those in machine I run and are likely the same for entire line of Yama lathes, just be aware of some odd English translation, such as "living tool" aka "live tool" or rotary tool.

nice find! i have the fanuc lathe manuals that i've been looking through a little bit, but not quite comfortable yet to do anything drastic. i did try the nakamura post and it seems to work best so far, still need to change some M codes manually but a good start.

Most basic edit you can do is to print M code list from the PDF manual, open post and scroll down to where list of M codes is, look at the function of each and just replace with one your machine uses.

I know Visual Studio is helping hand, I just have to take time to learn another process of getting something done in way I am not yet familiar with and, to me, getting my post more refined is not all that critical because my filter before running program in machine is NC editor and back plot.

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
