Checking an CWW circle

sscandlon

I am struggling with what seems to be a simple part it’s three holes all in line the datum’s are based on one circle that’s measured CWW but when I try to do an auto feature the probe crashes into the part and then it can’t locate the other two holes.  any suggestions on how to set up the alignment again it’s based off of the middle outside radius and the small bore to the right of the middle bore.

    yes define the clearplane after your a3 manual alignment. Edit : after the A3_DCC1

    I changed it to .02 is that why i was having those issues with it crashing into the part ?

    no it was crashing because you weren't using any clearance moves or avoidance moves

    I had the clearance cube activated . If i put the  "CLEARP/ZPLUS,0.5,ZPLUS,0,ON" after the third alignment will that fix it ?

    Never used the clearance cube so you may have to turn that off, once you define your clearplane you will have to go in and add a "MOVE/CLEARPLANE" before each feature. similar to this.

    Ok I'm starting over from here how would you align this and where would you add the clear plane ?

  • 0 in reply to sscandlon

    Alignment looked okay. After you do your alignment and set the Z Axis, define the clearplane, then whenever you do an auto circle, or any auto feature it will automatically put a move/clearplane move in before the feature. 

    Probably don't have to restart, all you need to do is define the clearplane and put a move/clearplane before your features.

    ok thank you ill let you know if I've fixed it !
