Do changing Target Pts "move" the probe along a surface?

NeverSayNever
I'm having problems understanding the code below.

My first question is this: By changing the TARG "X" values for each subsequent vector point, is this, in effect, moving the probe along the surface in the X direction? That is, does this code take actual hits in different locations? Even though the THEO values are EXACTLY the same? This part of the program is attempting to measure the D.O. between two vanes.

My second question: If this is indeed "scanning" along the surface, I'm wondering why this approach is advantageous over , say, just changing the THEO value from point to point.

First post. Appreciate any insight.

    Answers in RED above.

    If you have a flat surface, where the vectors and location along the vector are the same value, the T value will calculate along the vector and the values would be correct.

    What you code is doing though, I don't know. You can see that all of the nominal are the same, and the measured values differ. I'm not sure of the reasoning behind it though. Laziness, sloppy programming? Maybe they were attempting to do something specific that happened to be unorthodox.
  • Thanks for the quick reply. I appreciate you confirming that.

    The surface is not exactly flat. It's a small portion of the convex side of an airfoil vane. It does have SOME curvature to it. Even over this small of an area.

    The idea behind this code --- and I've only shown part of it --- is to calculate the opening between the convex side of one airfoil to the concave trailing edge of an adjacent airfoil. The programmer took a single point on the adjacent airfoil. All the points from this convex "scan" are supposed to be measured to that concave point. The distances are to be compared, and the shortest distance gets reported as the D.O. (diametric opening).

    I'm still scratching my head as to WHY this "Move the Target" method would be better than creating individual, unique THEO vector points.
  • With this approach the nominal distance between each point and the point on the opposing vane will be the same. You could then dimension each distance and take the one with the smallest deviation value. I would assume that the programmer chose the THEO value for this point that gives a nominal that matches the print and then just modified to target values to search along X to find the points with the smallest deviation as compared to this nominal. There are plenty of other ways you could do this as well but I think this could work fine.
  • Can some please explain these ACTUAL results to me?

    It looks to me like the intent here was to inspect .050" on either side of the THEO point, using the TARG "X" value as an offset. We just now measured this on the CMM. If the TARG X value is changing .25mm every point (.010"), how come my ACTL "X" values are always the same? I don't understand. I would expect the ACTL X values to be very close to the TARG "X" values. No?

  • Wait a second. Is the point taken for each TARG hit being projected back to the THEO surface normal vector? That would explain WHY all my ACTL "X" values are the same. the ACTL "Y" and "Z" values differ, but the "X" values are all the same.

    Problem is, when I take these ACTL XYZ coordinates and plot them out in UG, it "looks" like all the points are right on top of each other.

    Is that what TARG is doing? Projecting back to THEO? If so, can that be turned off, so my ACTUAL XYZs are REALLY the actual XYZs?
  • Yes, you can by changing SNAP=YES to SNAP=NO.
    It’s on for a reason and you might not get the results you want by turning it off. Have no idea what the part looks like therefore I have no suggestions.
