Combining multiple Cones into one cone

NullTie
​I've seen different variations of this question asked but I can't seem to find my exact predicament.​
I have a small part that I'm inspecting and the only way I can probe it is to go around the part at 4 different angles using cones.

What I'm doing is, pretend that these cones are 90° included. I'm setting my probe angle to A45B0, probing the cones, then A45B90, probing the cones, A45B-90, probing the cones, then finally A45B180 and probing the final cones. After this, I create a constructed set using all the cones and dimension them with a profile tolerance(.002'). Now from what I can see, our parts look good, in terms of angles and position, but for whatever reason the profile tolerance is out of tolerance.

Is this the best method to use to inspect these features?


Is there a way to combine these cones in order to use the measured points into a larger cone?

Example of the part (Not the actual part):

  • Older version of PcDmis:
    Construct a cone BFRE.
    Select the four pieces and hope the math works since it is using four centroids.
    After each one, add .hits[1..conX.numhits] where conX is the name of the feature you are typing that after.

    IF the math doesn't work, select things until it does work.
    Then add the .hits statement above and delete the features that should not have been included in the first place but you needed to get successful math.

    Newer version of PcDmis:
    Construct BFRE
    select the cones in the window
    In the graphics window click the points individually and it will use the points for you.

    You are rotating the head, so you want to recomp (the RE part of BFRE).

    I've done this with speherical bearing races and dovetail grooves (like you're doing) without issue in the past.

    You want to have points that have a common Z, so you have circles of points.
    If you have a newer version where you can click the points in the graphic window, click them in circles instead of clicking them by cone segment.
