Cone Diameter

figure 1, sub menu

Another very powerful feature available with the Cone analysis tools is the ability to locate the height off the PCS Base Plane that a specified diameter exists at. For example if measuring a cone that defines the seating surface of a valve and the dimensional requirement is to measure the height where the cone has a diameter of 3.500”. We would use this tool to extract that solution from the measured cone.

When you have measured the cone, right click on the cone in the inspection report to activate the sub menu, see figure 1. From the submenu commands, choose [Cone Diameter], see figure 2.

Enter 3.500 in the Cone Diameter Setup Tool and press <Ok>. Remember, this is the distance off the current PCS. It is expected that the axis of the cone is parallel to an axis of the current PCS. You may need to establish a PCS using the cone as the Orient to ensure accuracy.

In the example shown in figure 3, The diameter of 3.500" resulted in a diameter above the original Cone. This diameter can have a tolerance applied to it and be used in constructions.

figure 4, Reported Cone Diameter

In the inspection report, the Cone Diameter reports the nominal Diameter and the effective depth where the diameter exists as shown in figure 4.
