CMM Accuracy + Machine Accuracy - iSixSigma

Mar 18, 2005  Accuracy is simply a variance. The square of the total variance is the sum of squared of separated variances. For your example, CMM Accuracy (0.0002) and Machine Accuracy (0.0003), we have a global accuracy equal to 0.00036=SQR [ (0.0002**2)+ (0.0003**2)].Regards,DANG Dinh Cung [email protected]
