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.
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.
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
