One point Alignment using CAD

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.

  • +1 here. One touch set ups were the way I was taught right off the bat even before I went to the PcD classes. I strictly program offline off the CAD model so I'll bring my model in (usually in local coordinates) and put an operator comment in with instructions how to line the datums up with the machine axes or otherwise set up the part. Then I'll program my datums with auto features and the necessary Move To's. If I'm picking up datums on a curved surface or using datum target points, I'll pick up a my datums a couple of times. When that's all said and done, I'll jump back up to the top of the program between the Op comment and first datum feature and find a feature on the model that's easy to identify. Usually it'll be a hole on the floor so I'll have an operator comment to take a "touch just Y pos of the pilot hole on the floor". I set X, Y, and Z on this touch, let the Demon auto update everything below and go to DCC. I'll then level my part, let the Demon auto update, rotate and update and finally set my origin and update. Sounds more complicated than it really is but it makes the Demon earn its keep by doing a lot of the heavy lifting.
