Need Help!- Tool Wear Adjustment

[nfrees114]

Hey all- so i have had my Haas VF-2 for a few months now and am trying to figure out where to put in for tool wear. I know on the offsets page it has a wear and geometry column. well i've put #'s in those columns and nothing has worked. see my problem is i have a brand new 1/4" end mill. well its cutting .005" big so i need to cheat it down to a .255" end mill. i thought you could just put a -.005" in the wear column and it would do that. I didn't know if you had to post a code in the program in order for it to work or what? i do my programs through bobcad so thats why i'm not sure how to cheat the tool offset. any help would be greatly appreciated.
Thanks!!

It sounds like your program isn't using cutter compensation at all.
Do you know how to hand code a cutter comp move with g41/42?
Is your program calling the correct D#? (the Haas has a setting that will allow the tool h# and D# to be different)

If using cutter comp it would be +.005 to tell it that the tool is .005 larger.
I use only the GEOM column per the Haas applications guy who showed us how to operate our VF-2SS.
