Each measurement is only an estimate and therefore always entails some sort of error.To make sure that our data is clean and reliable, we should always check our measuring devices. Because no matter how intelligent your machine is, it operates on the assumption that your data is not rubbish. So we need to estimate how good the measurements are in relation to the measurement process. This is the increasingly topical Measurement System Analysis – MSA.Thanks to ISO 22514-7, the requirements of VDA5 in Europe and AIAG in the US are finally coming together in one standard. Yarvyn is an indispensable help as it complies with the aforementioned ISO standard, i.e, it calculates the QMS and QMP. Also, it delivers even Cg, Cgk, GRR (R&R) for both continuous and attributive values, thus providing better guidance for an experienced metrologist.
