Hi All
Got a Haas VF TM2
Need a little help with setting the offset on a tool.
I did a pocket with a .5 End Mill which came out .005
undersize--could you guide me in the right direction
in setting an offset to compensate for tool ware ??
Thank you very much--- Rick

Well, first give us some code. There are several ways you can accomplish this.

Here is a bit of the code to see no G41 is output
I am using Bobcam to generate the code--
I think i first need to find out why Bobcam is
not giving me a G41??
(FIRST CUT - FIRST TOOL)
(JOB 1 POCKET)
(FEATURE POCKET)

(TOOL #1 0.25 1/4 FLAT ENDMILL - LONG)
N02 T1 M06
N03 G90 G54 X0.1067 Y0. S1500 M03
N04 G43 H1 D1 Z0.3 M08

Looks to me like you are just roughing the pocket out. Check your settings, there should be an option for finishing, and that should get you your comp

[kkburr73]

your not using any comp. If you had a G41 that would activate cutter comp. Then if you cut was .005 undersized you could use comp in your tool data. -.0025 or -.005 depending how you have your parameters set up. right now your just cutting with now comp.

[djr76]

I know in Mastercam there is an option to either let the "Control" or "Computer" handle the cutter comp. If Control is chosen, then G41/G42 is posted.

Thanks Guys--
I am having someone in Bobcam look at it know
why it does not output G41 when "it seems i am
doing everything Right---Will let you know--

In the mean time i would appreciate an explanation
of the D# and H# Thank you---- Rick

[djr76]

The D# is referring to the tool diameter in the offsets page. The H# is the tool length reference to what ever Z plane you set your tools on in the offset page.

djr76--

Thanks a lot for the explanation
Very helpful-
Thanks again---- Rick

To ALL--
I finally got the reason why--
In Bobcam--you can not get a G41 if you are doing a pocket alone !
You need to be doing a Profile (with the proper settings)---So if it is
a pocket for a bearing that you are trying to adjust--You first
pocket out--leave enough to clean up with a Profile.

That is what i got so far---Now i will go see how the Haas likes it ??
Thanks for all your interest and help----Rick
