I am milling a .460 hex on the end of a shaft in G17 XY plane and it is .4615 I cannot get tool wear comp to work. The dealer's application engineer said machine will only read tool nose radius wear as a positive value. So we reposted the program telling the machine that a .250 end mill was .240 and put .010 in nose radius wear with the same result no wear comp. hex is now .4515 Anyone know how to get wear compensation to work when milling on a lathe. There is no spot for a D value as there is on a milling machine.

Are you cutting the feature in Y-Axis mode or C-Axis? You have a G41 at the start of the cut, correct? The tool call should be T010101 (Nose radius comp, turret station, offset number)

You need to program to the edge of the endmill and not the center. Then if your using a .250 endmill you'll put .125 in your X tool radius comp.

Y Axis T090909 with a G41 all from Master cam. I did get it to work on main spindle programming for a .240 end mill and putting comp at .004 for a .250 EM finished it on size, but for some reason comp is not working on sub spindle. Hex is cut to -.020 the exact size for a .240 EM

No Mastercam posts code to cutter comp for a .250 endmill with nose radius wear set to zero. I'm looking to get nose radius wear to function because endmill is actually .2485

Can you post your sub-spindle code if you are still having issues?

I know it's a little late, but are you putting your tool radius values in the fields on the Spindle 2 page of the offsets?

on LB's there isn't a set of Spindle 2 offsets like on a Multus or Macturn

This is what it looks like if when I programmed it for my Multis in X-Y mode using cutter comp. Note the Y+.230 & Y-.230 for your hex diameter. Tool diameter should not be included when programming on a Okuma millturn. 1/2 your endmill =.125 diameter would be put into your X or Z tool nose radius comp.
