Read point alignment.

Good day all,
I am attempting to start programming using a read point alignment. I am either not doing it right at all or I think the issue might be that I am using clearance cube.

any help is much appreciated.

  • You're almost there. The issue is with your alignment. Please see below:


    COMMENT/OPER,NO,FULL SCREEN=YES,AUTO-CONTINUE=NO,
    Put center of ball at center of corner near Datum B
    Hole. Put ball as close to part as you can get by eye.

    Press okay to begin automatic measuring.
    Goodluck.
    MODE/DCC
    READPNT =FEAT/POINT,CARTESIAN
    THEO/<0.197,-0.345,0>,<1,0,0>
    ACTL/<2.986667,14.857676,-14.77957>,<1,0,0>
    READPOINT/
    A1 =ALIGNMENT/START,RECALL:STARTUP,LIST=YES
    ALIGNMENT/TRANS,XAXIS,READPNT
    ALIGNMENT/TRANS,YAXIS,READPNT
    ALIGNMENT/TRANS,ZAXIS,READPNT
    ALIGNMENT/TRANS_OFFSET,XAXIS,-0.197
    ALIGNMENT/TRANS_OFFSET,YAXIS,0.345
    ALIGNMENT/END


    Here is an example of how I started a program yesterday that works just fine. DCC Mode comes first the way I program. Not sure if it works elsewhere, this is just what I have been taught & what works for me. Test it if you'd like. Any how..
    When you import your model into PC DMIS, the trihydron will be in a specific spot. This will probably be a different spot then where you want your read point.
    Look at my alignment. All I did was make the read point where I wanted & then translate the read point back to the trihydron's original location when I imported the model. (hint: all you have to do is make the read point your origin and then translate back the opposite of your read point coordinates. My readpnt's X theo was 0.197 and Y theo was -0.345 so in the alignment below i just highlighted the read point, hit the origin button, and then translated the axees that moved back to the original location on the cad. in this example, Z never changed so I did not have to do Z translation in my read point origin).

    Once that is set, use move points or move increment to get around the part to make a legit physical origin, then turn on your cube, and then you should be good
