    Cutter Comp Alarm Issue

    I am a CNC rookie, so be patient with me. I have a HAAS TM 1, the problem I am having is an alarm saying the tool is to big when I try to run finish pass for a pocket. I am running a .5 inch endmill which is the same tool I am using for the roughing pass. Here is the NC code I am running, it was developed in FeatureCam.
    N920 ( FINISH POCKET POCKET1 )
    N925 G1 G54 G90 X17.1532 Y-1.9104 Z-0.51 S2750
    N930 G41 D04 X17.1277 Y-1.8662 F17.9
    N935 G3 X17.0879 Y-1.8344 I-0.1043 J-0.0896 F8.9
    N940 X17.0879 Y-1.8344 I-0.0879 J-0.1656
    N945 X17.0879 Y-1.8344 I-0.0879 J-0.1656
    N950 X17.0481 Y-1.8188 I-0.0879 J-0.1656
    N955 X16.9973 Y-1.8151 I-0.0353 J-0.1329
    N960 G1 G40 X16.9486 Y-1.8301 F17.9
    N965 G0 Z1.0

    The alarm goes off on line N930 when cutter comp starts. I am wondering if the setting in my mill are correct? From my understanding the following settings affect cutter comp in the HAAS controller (here are my settings):
    40-Diameter
    43-A
    44-50
    58-FANUC

    I hope I have provided enough information. Apperciate any help.

    Happy Veterans Day

    What do you have in D04?

    I am assuming you want to know the tool diameter offset I have set for D04? It is currently set to .498.

    Correct.

    It appears as if your program is for the center of the cutter, not the actual part coordinates. If your tool is on size, you should have 0 D04. If your cutter is 0.002 undersize, try putting -0.002 in D04

    I think I understand. When I go to the offset page under diameter I have 2 columns geometry and wear, currently I have the Tool 4 at .498 under geometry and 0 wear. Are you saying change this to -.002 under geometry or put that in the weqr column?

    Thanks for quick response
    I went ahead and tried -.002 under the geometry column and it did exactly what I wanted. So now I have another question, my roughing pass worked fine with my tool diameter offset set at .498 if I leave this set to -.002 and use this same tool for my roughing pass will I have a problem? Here is the code for my roughing pass:

    It looks like you've programmed the roughing pass with cutter comp set to 'computer' (or whatever terminology Featurecam uses). In other words, there is no cutter comp code (G41 or G42) in your roughing pass, and that's why it worked.

    Then you programmed your finish pass with cutter comp set to wear, which is why the full size of the endmill was too big to have in your offset page. You can have your -.002 in either column, but putting it in the wear column just makes more sense to me.

    I would set -0.002 in the GEOMETRY and 0 in the WEAR since you're starting out with a 0.498 cutter.

    All of the CAM systems that I've used don't output cutter comp commands (G41/G42) when roughing simply because there would be too many areas where interference alarms would occur, but they do output G41/G42 during the finish pass.
