The recognition system for a geometric errors and recognition method for a geometric errors

摘要

A recognition system for a geometric errors and a recognition method for a geometric errors, which simplifies a calibration of a position measurement sensor (13), so as an improvement in a positioning accuracy of a machine (1) to improve, are provided. A measured value for measuring a means point start value (a starting position) of a target ball (14) is used to move the calibration at a distal end portion of a probe head (13) in the radial direction to carry out. Accordingly, the calibration of the probe head (13) simultaneously with the measurement of the means point start value to be carried out.
