The CMM calibration process is there to check that such occurrences do not happen. However, as metrology equipment wears, measurement dimensions can shrink or grow accordingly. The best of the machines used by Verus Metrology has a base accuracy from ⌙0.002mm. So, for example, any measurement activity conducted at Verus Metrology has an inherent uncertainty to it. Therefore, it is important CMM calibration tests are carried out for each position the probe will be working in.
The process of a CMM calibration test is primarily to ensure the probe used during future measurement activity remains accurate throughout each orientation required. The process involves the measurement of verified artefacts in various orientations to prove the metrology machine is measuring accurately. Essentially, CMM calibration exists to prove the measuring machines used to perform the process of measurement are meeting the measurement standard and certainty.
CMM calibration is the verification and adjustment of the CMM and any corresponding measuring equipment to a known standard. Consequently, to maintain the CMM’s sophistication, it is vital such measuring tools are recalibrated at least once per year. Undergoing regular CMM maintenance allows metrology service providers like Verus to utilise accurate calibration data to ensure misalignments are determined and either corrected or integrated into the data results.ĬMM’s are the most advanced dimensional measurement instrument used throughout the industry today. It verifies the level of accuracy the measuring machine will perform to. Therefore, a CMM calibration test is vital in ensuring the reliability of a CMM. But why is this necessary? The answer: A CMM can have errors along 21 different measurement axes. To provide both services to a high standard, it is important the Coordinate Measuring Machines (CMM’s) go through annual recalibration. Additionally, Verus’s sub-contract metrology services provide accredited and traceable verification and certification to a wide range of global MedTech and Pharma clients. It is also vital to ensure there is no external influence on the component because of the fixture. This is where the bespoke fixtures are verified and certified to ensure they remain fit for purpose and perform with repeated results during each measurement process. Therefore, one of the key stages in creating Verus’s metrology fixture solutions is the qualification phase. For example, before an inspection fixture can be delivered, it is essential to ascertain it will perform consistently, with superior speed and accuracy capabilities.
Verus Metrology relies on expert technology and software to ensure the continued deliverance of precision-led metrology inspection fixtures and sub-contract metrology services.
