  • Highest point needed

    Hi All,
    Quick question, I have a domed part that I need to know the highest point. Very critical, accuracy needed is around a .0001" max. My problem is there is a radius around the outside edge. I plan on doing a Cylinder around the outside and picking up a plane as close to the outside as I can, but I don't know if these points would be the lowest points or not. So can I do a scan and do a MIN of the point, zero on that point and then do a MAX of the points for the highest point? Does this sound like it would work? I haven't started the part yet; still have about an hour before I can start. Just trying to get my mind programmed first.

    Thanks

    Are you familiar with the "Highpoint" autofeature?
    Lately, it occurs to me
    What a long, strange trip it's been.

      No, but I will look it up. So far what I wanted to do is working. I will try the "Highpoint" autofeature in the morning.

        hi,

        maybe command: array will help you?
        After that you can take max or min value.

          I did an array w/ min and max generic features. I just had a ton of points so I wasn't sure how many it would take. I got it to work.

            I have not used this feature. how does it work?

              I used to be high on life but I built up a tolerance.

                Ok, smartazs... even I could figure that out

                Since I have not used it, I was more interested in how it found the high point...

                    You describe a zone, circular or rectangular, within which the machine probes for the highest point in Z (given that the workplane is Z+) W/in that zone you also set the increment that the probe moves laterally. The low point can be found by selecting the Z- workplane. It works well but is slow. I prefer to take points and construct a highpoint plane.

                      High Point is time consumig(accuracy), but good

                        That would assume that you have actually probed the highest point.

                        Does this work iteratively? Does it go back and forth "looking" for the highest point?

                        btw, thanks for the answer.

                          Yea. It probes multiple points depending on the values that you input. I have found it very valuable when it is important that I get the true High or Low point either on an edge or surface.
                          It will probe in a circular (spiral) or coordinate method depending on what you set up.
