Because the three-dimensional triggering type measuring head has a pre-stroke error, an anisotropic error and a measuring head eccentric error, the radius value of the measuring head which needs to be compensated is different for different measuring speeds and different measuring directions, and the corresponding angle of the measuring head is calibrated according to the normal vector of the measured point.
The gauge head calibration is the basis for ensuring the measurement accuracy, and is an indispensable action before measurement. In the current calibration process, measuring points on a standard sphere with known contact positions of ruby on a measuring head are used for sending out measuring signals to obtain coordinates of the center of the measuring head, and then accurate measuring coordinates are obtained by compensating the radius of the measuring head in the direction of a measuring normal vector, namely, the difference between the actual measuring value and the theoretical measuring value of the measuring point on the standard sphere is calculated and used for compensating the deviation generated by the measuring head in the subsequent part measuring process.
