Fanuc OM tool radius compensation with table A using Fusion 360

[Dustydude]

Hi All,

My old fanuc OM mill does not have the separate columns for compensation it only has one long listing which I use for tool length H. I know from reading threads here that conventionally I would use line 1 for tool 1, H1 & then say plus 50 allocate line 51 for tool 1 radius compensation. I get this but now I'm very confused how fusion will handle this as it outputs a D line but it will default to D1 not D51.

Other than going into my program to hand change this is there a way to do it? Is it a post change?

I have also read I could possibly update my parameters (i think 907) to enable a D column. Is this possible

Also can anyone help me mod the standard Fanuc post to have M06 & T# on different lines as my Fanuc wont accept them on the same line

Best wishes

Dusty

OM will accept D as well as H for Cutter Comp. Not sure if this is true of all versions of OM but I know it works for OMC. Dig into your parameter manual as this function is controlled by parameter. Sorry don't know which one off the top of my head.

Can't help on Fusion mods.

Hi
Can anyone else help me with this and it's interaction with fusion so I'm able to use tool compensation when post processing from fusion?

I also can't help with fusion so don't get mad at me as I respond.

Regarding parameter, a 0m will take D or H for g41/g42 when parameter 36 bit 6 is a 0 (x0xxxxxx). If a 1, only D will work with comp and H will work only for tool length.


We use gibbscam and it has a spot when you create the tool to specify a value for cutter comp. We use 60 above. I would be surprised if there wasn't somewhere you could do the same in fusion.


My g code editor (a really old seat of predator cnc editor) has "math functions". In our case, if my code output was D1 for T1, D2 for T2, etc, and I wanted to change them all quickly, you can just tell it to change all diameter comp values by a certain amount; in my case +60. Perhaps you can do that in your editor as well.
