  • Finding the lowest point

    I have a Center Post that is formed from a welded tube. The axes is the ID. Two given diameters from two different cones. The setup is not the problem. What I would like help on is this. The end of the tube is where X axes should be set, but at the lowest point. The way the tube is formed. The end of the tube is not real square to the axes. I would like to take a number of points on the end of the tube. Is there a way to for the software or script that someone knows about to find the lowest point. I know you can construct a high point plane. Thanks for the Help.

    You could use something like this.........

    PNT1 =FEAT/POINT,RECT
    THEO/212.946,77.943,-454.551,0,-1,0
    ACTL/212.946,77.943,-454.551,0,-1,0
    MEAS/POINT,1
    HIT/BASIC,212.946,77.943,-454.551,0,-1,0,212.946,77.943,-454.551,USE THEO = YES
    ENDMEAS/
    PNT2 =FEAT/POINT,RECT
    THEO/217.177,77.999,-454.551,0,-1,0

    HIT/BASIC,227.732,78.11,-454.552,0,-1,0,227.732,78.11,-454.552,USE THEO = YES
    ENDMEAS/
    ASSIGN/V1 = PNT1.X
    ASSIGN/V2 = PNT2.X
    ASSIGN/V3 = PNT3.X
    ASSIGN/V4 = ARRAY(V1,V2,V3)
    ASSIGN/V5 = MIN(V4)

      I've had a similar situation where I just took a lot of hits on the surface, look at the x, y, z data in the part program and pick the lowest one and delete the rest.

        ASSIGN/V5 = MIN(V4)
        This is the proper way to do what you want. Also this:

        ASSIGN/V1 = MIN(ARRAY(PNT1.X,PNT2.X,PNT3.X))

        This will not account for part variation.

          Oh yeah, create a generic point using your variable as the X value and then translate in X to it.

            IDK if you're trying to avoid using a high point plane but you could use one and change the work plane to ZMINUS (if applicable) to get the low point.

              Thanks Inspector212 that worked great. We had to figure out the generic point and then how to assign it back to V1. I have 30 parts to measure and this will help. Thanks again.

                Might be related to high point of a plane...............
