  • Thickness

    I need to measure thickness of material on a corrugated surface. I am trying to use the measured x,y,z,i,j,k of a surface point to vector in from the opposite side of material to get an accurate thickness. My attempt to do this looks like this, but it is not working.

    PNT3 =AUTO/VECTOR POINT, SHOWALLPARAMS=YES
    THEO/PNT1.X,PNT1.Y,PNT1.Z,-(PNT1.I),-(PNT1.J),-(PNT1.K)
    ACTL/16.3134,10.1217,1.1747,0.9992069,-0.0380003,0.0119001
    TARG/PNT1.X,PNT1.Y,PNT1.Z,-(PNT1.I),-(PNT1.J),-(PNT1.K)
    THEO_THICKNESS = -0.3, RECT, SNAP = NO ,$
    AUTO MOVE = NO, DISTANCE = 0.197

    Any advice on how to do this correctly?

    Use ACTL_THICKNESS instead of THEO_THICKNESS. THEO_THICKNESS, when used in the auto features window, CHANGES the nominals of the feature. ACTL_THICKNESS leaves the nominals alone and, more or less, uses the thickness value as either additional probe comp or as less probe comp. With the nominals being feature values, it may not work correctly since it is assuming that the nominals alreaedy HAVE the thickness as part of them.

        I tried the actual thickness, no luck. It appears all the values for the targets are exactly what I wanted, yet the probe keeps crashing into the part.

          try a "Snap Point"...I've never used them myself..but, I hear that's what they are used for...could be wrong though...

            Maybe you need to use a little math in there for the vectors. Use
            -1*PNT1.I
            -1*PNT1.J
            -1*PNT1.K

              In my opinion, ball mike will be more accurate for measuring thickness on a corrugated surface.

              Anyhow, for the point in the opposite side could you offset the measured one (copy/pattern) and then F9 and just flip the vector?
