Calibration vs. Compensation vs. Certification
In many cases the terms calibration, compensation, and certification are used together, and are often used interchangeably by mistake. This generally occurs since traditional coordinate measuring Machines are often compensated every time they are calibrated or certified.
The process by which a measurement device is optimized to perform accurate measurements. This may be done through mechanical adjustments, as well as software corrections. In practice, this is often referred to as calibration.
The process by which one proves that a device is performing within factory specification. After calibration, a certificate is issued to authenticate the process, thus the use of the term certification.
FaroArm Lifetime Compensation
The FaroArm is able to maintain its certified accuracy throughout its usable life. It is designed to endure the typical stress and impact loads of a manufacturing measurement tool, as well as endure multiple transportation cycles.
Specialists at the FARO production facility perform the factory compensation. Using patented proprietary hardware and software, the true dimensions and kinematics of the FaroArm are determined. The results of this factory process are stored in the arm. The FaroArm is permanently compensated, such that it does not require periodic mechanical adjustments or software corrections during normal operation in the field, unless mechanical or electrical damage occurs. FaroArms requiring repair can only be serviced by specialists at an approved FARO facility.
The FaroArm is calibrated based on the ASME B89.4.22 standard. Specialists run each arm through a series of tests to ensure they meet all factory specifications.
The initial calibration is performed at the factory and, at a minimum, one annual calibration is recommended to ensure proper performance. It is up to your companies discretion and internal quality policies to determine the frequency and thoroughness of their equipment calibrations.
Although the FaroArm is factory compensated, you have the ability to change probes and individually compensate each probe after mounting to the FaroArm. This process determines the center of the probe tip relative to the arm coordinate system.
