Finding The Temperature Driven Center Point Drift of A Spherical Probe

For this theoretical experiment, I find the deviation of the center point of a spherical probe by adding conductive heat through hand contact. If you want to perform this test, you will require an infrared thermometer to monitor temperature changes, a stopwatch to track time, and a FaroArm with available standard ball probes.

First, let’s review the set up for the experiment. At stability, which is achieved once the FaroArm/ probe reach the stable operating temperature, you want to perform a probe qualification and ensure that it is within spec. After wards, one must perform a DRO to a measured plane while system is still stable (before you add conductive heat). Moving the probe around the measured plane should yield a deviation no greater than your qualification accuracy. If this is the case, then you have a valid plane/qualification.

Volumetric Inspection and Calibration of a CNC Machine

A laser tracker can be an ideal tool to check and calibrate a CNC machine. Typically, CNC machine tool calibration has been done by using a laser interferometer upon machine installation. This is usually a linear calibration that is performed separately on each axis. Typically, it is a repeatability calibration. In other words, if I send the machine to the same location over and over again, how accurately can it go to the same location in a single axis? A laser tracker can be used to volumetrically check not just the repeatability, but also whether or not the machine is traveling to the locations selected. With some newer CNC controllers, the error data can then be fed into the controller and self correct the machine motion.
