Calibration vs. error correction
Fontos különbséget tenni a kalibráció és a hiba kompenzáció között. A kalibráció a mérőgép pontosságának ellenőrzését és a referenciaértékekhez történő viszonyítását jelenti, anélkül hogy a gépen bármilyen módosítást végeznének. Ezzel szemben a hiba kompenzáció során a gépen vagy annak szoftverében tényleges beállításokat végeznek, amelyek célja a mérések során előforduló hibák korrigálása. Míg a kalibráció az aktuális állapot pontos megismerésére fókuszál, a hiba kompenzáció egy adott hibatípus célzott kijavítását szolgálja.
3 reasons to request a calibration for your CMM today
Over the past 50 years, coordinate measuring machines (CMMs) have become essential tools in machine tool shops and manufacturing around the world. Despite the increasing popularity of laser scanners and multi-axis scanning arms, CMMs continue to play a dominant role in quality control processes as the final verification of inspection results. CMMs are robust, with few moving parts. For this reason, maintenance and calibration of CMMs can often take a back seat, especially if their performance shows no noticeable degradation.
However, calibration of CMMs should be carried out at least once a year. This applies only to normal use; if the machine is used by several operators in several shifts, more frequent calibration is recommended. When the CMM is installed, the extent of all twenty-one kinematic error sources is determined. This process is often referred to as CMM fault mapping. Traditionally, the complete CMM calibration was performed by the original equipment manufacturer (OEM), but nowadays some independent metrology service providers (MSPs), such as ZALNER Engineering, offer full calibration for all measuring machines equipped with a RENISHAW controller. Calibration is a fully restorative process for CMMs that incorporates error compensation tables directly into the machine's software to restore optimal functionality.
Beyond compliance with the general requirements, there are many reasons to request CMM calibration today:
Validation
Even if the CMM is working as expected, calibration should be carried out at regular periods to ensure that the accuracy of the machine meets specifications. These processes are preventive: the aim is to detect and correct errors before they have a significant impact on the CMM's performance. CMM measurements validate all other processes in the factory, from CAD modelling to machining to periodic inspections. Regular maintenance can prevent problems from developing in time, avoiding costly machine part failures and significant downtime.
Post-collision recovery
Every time the CMM suffers a collision, it can affect the right angle of the axles. It is mandatory to check the machine axles after each collision.
Repeatability
For CMM measurements to be completely accurate, they must not only be true to the measured value, but also precise, so that the same point is found repeatedly when measuring the same part or other parts from the same series. Repeatability errors can be attributed to defects in other areas of the manufacturing process if they are not identified during regular maintenance and calibration. Chronic repeatability defects, such as air bearing friction or worn drives, may require physical repair if not corrected.
The performance of the CMM should be regularly checked (by calibration) to ensure its role as the final control for all other manufacturing processes in the factory. In addition to compliance with general specifications, these checks can help to identify deviations in time, before they exceed tolerances and lead to costly rejects or downtime.
