## Find Sphere Tool

The user must define the sphere that is being used when calibrating a Rotary Table. NC Gage needs to know the center location, diameter, stem vector and rotary table positions of the sphere. If these values are not known, these values can be defined in the Find Sphere Tool screen.

1. Access this screen from the Rotary Table Calibration screen. From the Rotary Table Calibration screen, press the Define Sphere Tool Information soft key to display the Find Sphere Tool screen.

2. NC Gage requires information to help understand where the stem of the sphere is. Position the probe so that it is on the exact (within reason) opposite side of the sphere from the stem.

3. Press the Read Probe Position soft key to learn this probe position.

4. Position the probe directly above the sphere so that when the probe is moved straight down, it will contact the top of the sphere.

5. Press the Read Probe Position soft key to learn this probe position.

Note: Steps 2 - 5 can use the same point, since the stem is below the sphere. The Return to Previous Step soft key can be used at any time to remove the last learned probe position when necessary.

6. Press the execute soft key . NC Gage will roughly measure the sphere using a 4 point finding pattern on the top. The user will be shown the measured values which can be accepted or rejected. The values can also be manually edited before accepting them if necessary.
