Post Processor for Fanuc OM

[Anonymous]

Hi everybody , i'm using an old CNC machine since 1989 with fanuc OM controller. I have a trouble with post processor for olds machine of my shop , it took me a lot of time to edit CNC program by replace or edit unnessary g  code and m code , so i'm very tired. I watched video tutorial to edit post but it's complicated to understand it . Someone can explain for me construction of post Fusion 360 or have a sample post processor for Fanuc OM? I'm really need it.

Thanks for read my post , my english not good so please help me.

Hello @Anonymous 

Thanks for posting. We have a manufacture forum which is exactly dedicated to CNC and CAM related topics. @seth.madore will help you by moving the post there. 

Thanks again.

@Anonymous  do you have some programs that are adjusted to suit what you DO need? The changes aren't that difficult to do, for the most part, once you have a grasp on how things work.

If you could get a concise and clear list of what's not working and what change you need to make, we can start looking at the post and make suggestions for modifications

I run a 1990's vintage 15M (0M). The generic Fanuc post processor worked for most basic things. Canned cycles will likely need to be added/changed to match your machine. For example, I had to change rigid tapping from G84 to G84.2/G84.3. Here is a link to my post processor: http://home.lewiscounty.com/~forhire/posts/fanuc15m.cps

Do you actually need the "Start of Path" and "End of Path" and "End of Program"?

[Anonymous]

Yes , i need edit the "Start of Path" and "End of Path" and "End of Program"  , because my cnc machines only understand g code look like that to run program
