PURPOSE: A method for correcting servo gain mismatch errors in consideration of a geometric error is provided to accurately correct servo gain mismatch errors by removing influence caused by a geometric error from bal-bar data. CONSTITUTION: A method for correcting servo gain mismatch errors in consideration of a geometric error is as follows. A path of a ball-bar test for defining the input of a sine wave to be applied to each drive shaft is planned(S100). A geometric error is separated from ball-bar data obtained from the ball-bar test(S200). Errors caused by servo gain mismatch are corrected(S300). |
