Gage Ball in Cone

Good morning. My part has a cone (lets say it's a countersink). The print calls for a gage ball to be placed into the countersink, then the location of the top of the gage ball is to be measured. How would I replicate this in PC-DMIS? I've probed my cone, obviously. Now I'm stuck...I want to construct a sphere with a set diameter to mate with the countersink.

  • It might be possible with the "construct circle from two lines/tangent lines". Scan a line on each side of the countersink, create a circle touching the lines with a set diameter. Workplane dependent.


    What about two autolines? On opposing sides of the countersink. Then construct a tangent circle using the 2 lines, correct?
  • Probe the hole as a cylinder or circle, or the countersink as a cone, and zero on it before you probe the lines down the side of the countersink. If the lines are off-center at all, the angle between them will measure incorrectly and it will shift the position of the constructed circle.
