Errors in the machine geometry of a coordinate measuring machine (CMM) can affect its measurement capability and result in product misclassification. These errors can be quickly identified by applying the analysis of variance (AOV) technique to data from a Latin square three-dimensional ball plate. Fifteen single sources of error in machine geometry for a cantilever design CMM are analyzed. The results of the analysis indicate that each error source has a unique pattern in deviation from nominal in the three axes and may be identified by the proper interpretation of the AOV. The methodology developed in this study has been applied to data from a cantilever design CMM. The analysis resulted in correct identification of error sources in the machine geometry. Rapid identification and correction of errors in machine geometry increases machine productivity.
