Laser trackers have emerged as one of the most vital aspects of 3D metrology tools for the manufacturing sector. Trackers have a reputation for supporting process precision at almost every phase, from machine to assembly, and for quality guarantee. Though laser trackers have state-of-the-art accuracy and precision, degradation or wearing away can occur quickly with increased usage. In addition, the performance will be affected over time. Henceforth, laser tracker calibration and maintenance services must be encouraged routinely, as suggested by ISO and OEM standards.
Assure OEM-Standard Specifications
Yearly calibration and maintenance services are the most effective method to assure that laser trackers cater to OEM-specified specifications. Calibration will measure the performance of the unit against the standard interferometer. When variations outside the tolerance range of OEM specifications are found during the process, it will be considered an error. Thankfully, the errors can be corrected via yearly calibration and maintenance services.
Make IFM/ADM Rectifications
The only way to correct faults or errors in Interferometer Measurement (IFM) or Absolute Distance Measurement (ADM) is by conducting routine and thorough calibrations based on OEM standards. IFM/ADM powers the measurement functions of the laser trackers. Without routine laser tracker calibration and maintenance services, the faults or errors in laser tracker performance will continue to grow, hampering the accuracy or precision of the measurement.
Rectify Minor Alignment Problems
There is a misconception that laser tracker calibration only deals with problems in the laser shaft. The reality is that laser tracker calibration helps evaluate and analyze every part of the unit for errors. The evaluation or examination of the parts helps identify the flaws which influence the performance of laser trackers. One such assessment is determining the alignment of every internal mechanism of the laser tracker. This ensures that no component of the tracker has shifted from its original position.
Update Software Programs
OEMs ensure that the firmware and logic functions of laser trackers are updated regularly. This is necessary to assure third-party software compatibility and enhance the units’ performance. Yearly calibrations and maintenance services ensure the laser equipment and tools function efficiently using the most up-to-date software. Software programs are required to be updated routinely so that bugs can be removed or fixed and performance is optimized as well.
Addressing Minor Issues
During the calibration process, the laser trackers undergo a complete assessment. Such assessments help to identify minor breakdowns and faults, thereby resulting in quick fixes. When routine laser tracker calibration and maintenance services are practiced, minor problems can be addressed easily before they become serious issues. When errors and other problems are not repaired or rectified, they start hampering accurate measurement and other performances. Moreover, it is cost-saving to fix issues when they are minor.
Conclusion
Routine laser tracker calibration and maintenance services are necessary to maintain the equipment’s optimal performance. Additionally, calibration also maintains the overall health of the laser equipment and eliminates future breakdowns. Thus, yearly calibration and maintenance services are highly recommended for maintaining the accuracy of laser trackers.
