One point Alignment using CAD

Virgil UK
Just recently I have been running larger samples of parts. The time has come for me to automate my program even more. One way of doing this is a "one-point" alignment on the part. I have tried this before but have fallen foul, I think it was because I wanted to keep the CAD datum where it was. Does anybody have any info on this or can suggest some options for me achieving this?

Many thanks in advance.

  • Keep the cad datum where it is, no need to EVER change it.

    Set the part/fixture up on the table, put directions in the program (pix too if needed) on how to set it up.

    Then, simply do a READ POINT (or single touch point) with directions of WHERE to do it. Set XYZ origins and offests, do CAD=PART, then go into DCC and measure an alignment close to where the point is, then do a real one using all the correct datums or pick-up features of the fixture.
