A calibration method of the three-coordinate measuring machine (3CMM) is presented. Two types of three-dimensional standard gage made by the authors were used for the calibration test. In this method, the error vector was directly observed and determined by comparing the measured value with the true value of the gage. The discrete distribution of the error vector was thus obtained. This method is convenient for machine shop applications. Based on the proposed method, the calibration test was performed on the 3CMM. To verify the accuracy of the calibrated 3CMM, distance measurements were performed using the gage blocks, and the measured values were corrected. As a results, it was clarified that the error correction using the result of the calibration test improves the accuracy of the 3CMM.
